001- How do I transfer files between my Apple and a PC or Mac?
The best, most flak-free way to move stuff between your Apple II and PC or
Mac is via a standard NULL modem transfer. (A NULL modem connection joins a
serial port of the Apple II to a serial port of a PC, Mac, etc. via a NULL
modem connector joining modem cables from each computer. Radio Shack and
ThinkStuff sell NULL modem connectors/cables.) The usual way to get the most
out of this connection is to have a telecom program on the Apple II talking to
a telecom program on the PC or Mac. For more information on standard NULL modem
transfers see Q&A 004 below.
A variation of the standard NULL modem setup is a software package plus
cable specifically designed for transferring files between computers. For
information on such a package, see Q&A 002 below.
Other ways of doing a direct PC-Apple II transfer include ADT and Ap2222;
and, for Mac-Apple II transfers, there is MacADT. These software packages
include programs for both computers-- e.g. Apple II and PC-- which let the user
do transfers via serial ports (ADT) or game port and printer port (Ap2222).
They are, mainly, intended for moving whole A2 5.25" disks. For more
information, see Q&A 003 below.
Another option is to use a BBS-- perhaps your own company BBS-- or an
internet website, ftp site, etc.. You upload from one machine and download with
the other. For more information about uploading and downloading, see the
Telecom-2 FAQs.
A completely different approach is to move files on diskette. For PC
transfers, this normally requires that either the Apple II or the PC have a
plug-in card and disk drive which lets it read diskettes from the other
machine. For example, an Apple II could have a PC Transporter board with a PC
drive connected; or, the PC could have a TrackStar board with an Apple II drive
connected. For more about TrackStar, see relevant information in Csa21MAIN1.
Depending upon model, installed OS, and available utilities, Macs can
exchange files with Apple II computers via ProDOS and HFS 3.5" diskettes. Macs
with the A2 plug-in board can handle standard 5.25" A2 diskettes.
A modified version of the above approach is for PC users to employ a
utility which allows writing to HFS diskettes.
Files can also be exchanged with PC's and Mac's using Zip disks. (See
Csa2ZIPTF.)
----------------------------
From: SuperTimer and Rubywand
If your other computer is a Mac, you can format a Mac HFS (standard) DS/DD
3.5" disk and the GS can read and write it if you have the HFS FST installed.
That's how I exchange files with a Mac...
On a PC, you can install a program called MacDrive 98. This program allows
Windows 95 to read, write, and format HFS volumes.
To transfer files from HFS media to ProDOS disk on the IIe, IIc, or IIc+
you can use A2fx or HfsLink. The IIe, etc. must have an 800k 3.5" drive
connected to access 800k HFS diskettes. This method would also work for IIgs's
which can not run a version of System supporting the HFS FST.
----------------------------
From: Ruud
For Mac users, if the file arrives in a .zip or .sit form, it's easier to
work with because it's 'protected' from being altered by the Mac file system
(i.e having a resource fork added). An .shk file isn't protected since that is
a native A2 format.
Then it's a matter of getting the file onto a Mac *with an old-style disk
drive*, mostly the ones that 'suck your disk in' by themselves, but some later
ones - mainly in 68k machines, Powerbooks seem particularly good - work as
well. Powermac drives are not reliable, while a 68k Powerbook or SE/30 works
fine.
So, after getting it onto the 68k, I unzip/unstuff the file to obtain the
contained .shk, etc. files and let them be processed by ProType, which restores
A2 file types. Then I put them onto a ProDOS disk mounted on the 68k Mac (using
system 7.6.1) and restart ProType and let it change the types on the A2 ProDOS
diskette again just to be sure.
After booting the Prodos disk on the Apple II, it is just a matter of
starting Shrinkit v3.4 to unshrink any .shk files.
----------------------------
From: MDRipley37
For Mac users, there is a shareware utility named "][2Mac" for
transferring 5.25" diskettes from Apple II computers to Mac as IIe- and Bernie
][ the Rescue-compatible disk images. It works for transferring images from Mac
to Apple II diskettes, too. I have used it for over a hundred transfers with no
problems and Apple II disks that boot up just like the originals.

002- How can I transfer and convert word processor files from an
Apple II to a PC Microsoft format (DOS, Word)?
There is a Sequential Systems package complete with cable named
"CrossWorks" which lets you transfer Appleworks, Word Perfect, text, and other
ProDOS files to a PC. It transforms them to a variety of PC formats (e.g.
AppleWorks to/from Microsoft Works). An alternative is to convert the Apple II
file to plain Text and send it that way.

003- I've heard of ADT and ap2222pc. How do these packages work for
transferring Apple II disks between an Apple II and a PC?
Yesterday I downloaded ap2222pc.zip written by some guy in Hong Kong. It
copies whole Apple disk images over to the PC, or PC to Apple, or individual
files back and forth!
You buy a 25-pin male parallel port connector and two 8-pin DIP sockets
from Radio Shack. He gives the wiring diagram for connecting 9 wires between
them. You type in a 6502 assembly program on your apple at address 300. Save
the program, shut things off, hook up the wire from your PC printer port to the
Apple Game Controller socket, turn them on (Apple first, then the PC), and run
his programs.
It works great! I've already made 26 disk images from my old Apple disks.
----------------------------
From: Paul Guertin, Sean Gugler, Paul Schlyter, Rubywand, Ronny Svedman
ADT (Apple Disk Transfer) lets you transfer 5.25" 16-sector A2 disks from
your Apple II to your PC. It will also transfer standard 5.25" .dsk disk image
files from the PC to a formatted 5.25" diskette on the Apple II. The connection
is a fairly simple NULL modem link between serial ports using standard cables
and adapters.
Transferred disks can be DOS 3.3, ProDOS, Pascal, ... . However, ADT will
not correctly transfer most copy protected disks to the PC; and, it will not
transfer ProDOS-order (usually .po) disk image files to the Apple II.
ADT is a pair of dedicated telecom transfer programs-- one for Apple II
running under DOS 3.3 and one for the other computer (almost always a PC; but,
there is also a version for Mac). The PC-side program is available in a vesion
for Windows 95, 98, Me (adt.exe) and one for MS-DOS (now named "adtdos.exe").
There are several versions of the Apple II-side program in order fit
different models and serial interfaces:
ADTssc- The current version (1.22) of 'standard ADT'. It requires that an Apple
Super Serial Card or compatible card be installed or that the Apple II be a //c
or IIc+ (which have SSC-compatible serial ports).
ADTcc- ADT modified to work with many, mostly older, non-Super Serial Card
serial interfaces. (Current version is 1.21.)
ADTgs- Currently at v.91, this is ADT modified to work with the IIgs modem
port. (ADTgs will, at present, do only PC-to-Apple II disk image transfers.)
ADT is practically always distributed as a .zip file including at least an
Apple II and PC program plus directions for transferring the Apple II program
dump file to your Apple II, setting up, and operation.
The latest distribution, ADT_2004.zip includes the three Apple II-side
programs, both PC-side programs, directions, and assorted support files.
Each Apple II-side program is a block of code (e.g. adt.dmp) designed to
be dumped from PC to an Apple II running DOS 3.3 via a simple Text transfer to
the monitor which requires no terminal or other special software on the Apple
II.
Once both sides are installed, ADT transfer speed typically ranges from
9600 baud through 19,200 baud.
----------------------------
From: Delfs
If you find you just can't get your communications software to transfer
that ADT file, then lets try it without any comm software at all. We will still
essentially make the IBM type in the program on the Apple II using the comm
ports of both computers.
This procedure will require an Apple Super Serial Card and the ADT and DOS
files on your PC. This instruction sheet requires that you have downloaded the
PC version of ADT and uncompressed it in a folder on the C: drive.
Note: This procedure may be modified to work on a IIc or IIc+ computer as they
have SSC compatible hardware built in, the trick is getting the cable wired
correctly.
For the Apple Computer---
1. Turn off your Apple II computer, take the lid off and rub the power
supply box 3 times for luck. (And to dissipate any static electricity
on your person.)
2. Set the SSC card for 300 baud.
Switches are as follows 0=off=down, 1=on=up
1001111 - 1101110
Just left of the rainbow colored cable there is a 'chip' with a triangle
on it. Make sure the triangle points towards the top of the card. If
it does not, lift the chip out of it's socket and turn it around. This
chip is a jumper block.
Note: You can use a standard modem cable between the SSC and your
Windows computer instead of a null modem cable if you change the SSC
jumper to point down instead of up.
3. Place the SSC card into slot two of your Apple II.
Note if you use a IIgs: Go into your IIgs control panel and set slot two
to 'your card'. Press OpenApple-Control-Esc at the same time to enter
the control panel. Make sure to press 'Enter' to leave a menu, NOT Esc.
4. Plug in the cable to both computers. (Properly wired cable is the
key.)
For the WinDoze Computer--
5. Uncompress the ADT122.zip into a folder with the name adt122 on the
root of the C: drive for convenience. (I use Winzip for ease of use.)
6. Boot up a DOS disk and get to a DOS prompt. For a Windows 95/98/ME
computer, use a 'dos window' by selecting Start/ Programs/ MSDOS Prompt.
7. Set up the port for communications. Type in the following command at
the dos prompt, replace the X with a port number, 1 or 2 where the
cable is plugged into the PC.
mode comX baud=300 data=8 stop=1 parity=n
Now--
8. Turn on the Apple IIe and boot up a DOS 3.3 disk and type the
following command.
IN#2
Note: If you do not have a DOS 3.3 disk, you can create one by sending
the DOS33 file instead of the ADT file, using these instructions to
transfer the DOS33 file, then following Rubywand's instructions on
making a bootable disk. (Took a really long time to transfer DOS33 at
300 baud before I could send the ADT program.)
9. Go back to your Windows machine and type this into your Dos Prompt
window. The first two lines move to to the folder where you have the
ADT files. Then the third line starts typing the file on the Apple II.
Replace the X with the port number, 1 or 2 as you did above.
cd \adt122
TYPE ADT.DMP>comX
10. You will see the ADT program being typed in by your PC. It will
even save itself to the disk before it is all done typing.
11. Once you have ADT on both computers, you should set the SSC to 19200
baud and work from there using the ADT program to transfer standard
DOS33 and ProDOS disks. The SSC card switch settings are as follows for
19200 baud.
0000111 - 1101110
I have verified this procedure several times and had no problems. Just
remember to do the IN#2 on the Apple before you do try and transfer the file.

004- How do I transfer files between computers using NULL modem?
You will need a NULL modem connector and each computer needs a modem cable
and telecom program. A IIe or II+ will also need a serial card.
____________ ____________
| PC or Mac | | Apple II |
| running a | | running a |
| telecom | <--modem--> [NULL modem] <--modem--> | telecom |
| program | cable [connector ] cable | program |
|____________| |____________|
"NULL modem" means "no modem". A NULL modem connector is just a pair of
connectors wired 'back to back' with a few lines switched so that each computer
views the other pretty much as though it were a modem. Radio Shack, Marlin P.
Jones, and other places sell NULL modem adapters in the form of small modules
or short cables for a few dollars; or, you can make your own.
Since a NULL a modem connection generally requires fewer control signals
than a connection to a real modem, there are many workable variations of this
setup. One pretty good try is to use a serial printer cable connected to the
Apple II-- for example, on a IIgs you can use a Mac Imagewriter I cable. This
eliminates the need for a NULL modem adapter. (You will probably need a Female-
Female plug adapter to connect to the PC* COM port or PC modem cable.)
____________ ____________
| PC or Mac | | Apple II |
| running a | * | running a |
| telecom | <--[Fem-Fem]--><--NULL modem--> | telecom |
| program | [adapter] cable | program |
|____________| |____________|
One possible disadvantage of this method is that signal lines may be missing
and you will not be able to get hardware handshaking. (Tests using the IW-I
cable on a IIgs showed no loss of speed under Spectrum or ADTgs.)
On the Apple II side, you can choose from several good telecom programs.
Since you would like to be able to do Z-modem transfers, good choices include
Intrec's ProTerm-A2 3.1 (Enhanced IIe -- IIgs), MGR Software's Modem MGR (II+ -
- IIgs), AnsiTerm (IIgs), and Spectrum (IIgs). You can also choose from among
many other programs. Generally, these support X-modem but do not support Z-
modem.
If you're running under a current version of Windows, HyperTerm works very
nicely on the PC side. (For sending Text files from PC to Apple under HT, be
sure to uncheck "send line enders" in the ASCII settings.) If there is a
choice of terminal emulations, it seems best to stick with something simple,
such as "ANSI" or, even "none", or, if available, "auto-detect". (For transfers
to an Apple II running ZLink, select "Auto-detect" in Hyperterm.)
A good NULL modemming program for running under DOS is Telemate, commonly
available as shareware. Many other telecom programs are available and work fine
under current Windows, old Windows, and DOS. Similarly, there is a good
selection of Mac telecom wares.
To do transfers, you just connect the modem cable from each machine to the
NULL modem connector. If your PC or Mac has a spare COM port, the connection
can remain in place without disrupting normal net connections through the other
COM port.

____ |______ ____________
| PC or Mac | | Apple II |

| telecom | <--modem--> [NULL modem] <--modem--> | telecom |

|____________| |____________|
If you can not use a separate PC or Mac port for your connection to the
Apple II, you can move the PC modem cable connection from your net modem to the
NULL modem for doing transfers or use a switch box.
For a GS, the recommended modem cable is a "high speed" type which allows
hardware handshaking and, if present, this option should be set in the GS
telecom software. The same is true for other Apple II's with serial ports or
boards (like the Super Serial Card) which can do hardware handshaking.
However, a "plain" modem cable-- one supposedly without lines for hardware
flow control-- usually works fine. (Often, the main limiting factor will be
your serial card or serial port hardware and the speed of your Apple II. Apple
II's with accelerator cards or chips can usually achieve better transfer rates
than unaccelerated machines.)
Set the same format (8-N-1), baud rate, and protocol (e.g. Z-modem) on
each telecom program.
Note: "8-N-1" means 8 data bits, No parity, 1 Stop bit. Today, most ports and
cables will support hardware handshaking; so, this should be the usual flow
control setting. (If it does not work, check your cable to see that connections
match those suggested for your Apple II and interface. If you can not get
hardware handshaking to work, then you may need to specify a non- hardware flow
control option for one or both of the connected computers .)
A good first-try speed setting seems to be 9600 baud. If you get errors,
try moving down to 2400 baud (or, in at least one reported instance, moving up
to 19,200). An accelerated GS running Spectrum can connect with modern PC's
running HyperTerm at 57.6k baud or better. An unaccelerated GS will top out
around 38.4k baud.
Note: Spectrum, ProTerm 3.1, Modem MGR, and some other newer Apple II telecom
programs do not require that you modify IIgs Control Panel settings for speed
and handshaking. Since Spectrum directly accesses the GS serial port, speed,
etc. settings are done in the program. (By the way, this frees-up Slot 2 -- the
GS modem firmware Slot-- for any peripheral card which needs to have its Slot
set to "Your Card" in the Control Panel.)
Note: On the PC, HyperTerm allows setting the Port Configuration-- i.e. Format,
Baud Rate, and Flow Control for COM1 or COM2-- for a particular setup which you
can save under a name, like "GSxfers.ht". Whenever you start HyperTerm to do
transfers to/from the GS, you need to Open GSxfers.ht (or whatever you name it)
in order have your setup in place.
Place each program in terminal mode-- often, this is the default mode. Or,
the particular telecom program may have menu items or buttons you select for
specific kinds of transfers.
Next, you will usually select the function (send or receive) on each
machine and the protocol. The protocol should be the same on both machines. Z-
modem is the best choice for most single or multiple file transfers. (Text
files can be an exception-- see the next question. A plain ASCII transfer will
circumvent most problems but is slower; and, you may need to send and
receive/capture files one-by-one instead of in batches.)
Finally, you will select the file or files to send or "Open".
At the start, some experimentation is likely to be involved in getting
your computer-to-computer transfers going. For example, you may find that it
matters which end you start first. (When using ZLink on the Apple II and doing
an X-modem transfer, start the Send side first, then the Receive side.) If your
setup works best starting Receive first, you may find that one telecom program
or the other does not give you enough time to start Send-- i.e. it keeps
"timing out". The fix is to change the program's "Time Out", "Inactivity
Delay", etc. setting.
Note: Some telecom programs may expect an end-of-send signal which the sending
program does not supply. Pressing CTRL-X or RETURN on the Apple II or ESC on
the PC often seems to work okay for terminating the Send.
----------------------------
From: Jeff Blakeney
You don't need to manually tell Spectrum or other modern telecom programs
to receive a file each time you do a Z-modem transfer. Just make sure that you
have Auto Receives turned ON. In Spectrum the setting is in the Settings/File
Transfer/Receive Options... dialog.

005- How do I NULL-modem Text files without getting garbage?
The main problem in A2-PC Text file transfers is that Text files created
by the PC use a CR _and_ an LF to end a line whereas Apple II-created Text
files use just a CR. So; PC files show up on Apple II displays with annoying
"#" or inverse "?" symbols; and, Apple II files show up on PC displays with
long, un-terminated lines interspersed with block symbols.
For PC-to-A2 Text file transfers, Z-modem, X-modem, etc. usually work fine
if you have some way to deal with the extra Control characters, mainly line
feeds. On the GS, Appleworks 5 does a good job of automatically cleaning out
such garbage; and, Text editors like ShadowWrite and CoolWriter have options to
quickly strip out offending line-feed Control characters. Some telecom
programs, including Spectrum, have Text editors which can strip out Control
characters and perform other manipulations to clean up a file.
An alternative is to do a plain ASCII Text transfer. (The PC telecom
program should be told _not_ to add line feeds or "line enders".) Depending
upon your A2 telecom program, the result may be saved from your Capture Buffer,
captured directly to an on-disk Text file, or selected and saved from the
Scrollback buffer.
Similarly, for A2-to-PC Text transfers, you can use Z-modem or some other
block transfer protocol if you have a PC utility which can convert Apple II
text to text PC's like. For example, one way to send several Text files is to
put them in a .SHK file, Z-modem them to the PC, and use Nulib (v3.24) to
unshrink the files in PC Text format.
Otherwise, you are probably better off doing a Text transfer. Set your A2
telecom program to "send LF's". If there is a "Prompting" option it should be
OFF. Do an "ASCII Text", "Plain Text", etc. Send. The PC telecom program should
be set to Receive Text if this option is available. If it is not, you will be
able to select and save the text from the PC program's display or save the text
from some capture buffer.
Some programs with a "Receive Text" option may expect some end-of-send
signal which the sending program does not supply. Pressing CTRL-X on the Apple
II or ESC on the PC often seems to work okay for terminating the Send. For
example, Telemate will ask if you wish to abort the transfer-- you answer
"Y"es-- but, the file will still be saved on the PC.
Other programs may expect you to click something to signal the end of a
transfer. If you are using HyperTerm to receive text on your PC, you select
"Stop" in the Transfer--Capture menu to end the transfer.
----------------------------
From: Edhel Iaur, Esq.
Appleworks 5.x seems to do a pretty good job of cleaning up text files
from the net. (e.g. it automatically clears out the annoying LF's which show up
in most text file viewers.) There is, also, a standard Awks macro which will
get rid of end-of-every-line CR's.

006- Does anyone have directions for making a "NULL Modem" cable?
A typical NULL modem is two Dsub 25-pin female sockets (call them "A" and
"B") wired back-to-back as follows ...
Socket-A Socket-B
2 -> 3
3 -> 2
4 -> 5
5 -> 4
6 & 8 -> 20
7 -> 7
20 -> 6 & 8
Note: 6 & 8 are connected at each socket. (That is, if you are making a cable
instead of using back-to-back sockets, you do not want to run 6 and 8
separately to pin 20 on the other socket. For back-to-back sockets, it's okay
to run separate short leads if you like.)

\ 25 24 23 22 21 20 19 18 17 16 15 14 /
`------------------------------------'
If you can find a couple old-style Dsub-25 plug casings, the sockets can
be mounted and the casings can be glue-gunned together to make a nice compact
unit.
For Apple2-PC (or Mac, etc.) transfers, you plug the modem cable from the
Apple II into one side of the NULL modem and the modem cable from the PC into
the other side. If the PC has a 9-pin serial port connector, use a 9-to- 25
adapter cable to connect to the NULL modem. Similarly,for Mac users, if the Mac
cable has a special connector, use a converter to a male Dsub-25M connector for
plugging into the NULL modem.
Dedicated IIgs NULL modem cable
The usual IIgs NULL modem cable consists of a High-Speed IIgs modem cable
connected to a NULL modem adapter which connects to a modem cable coming from
the PC. If you want to 'roll you own' single piece IIgs --> PC cable for NULL
modem connections, here is the pinout info:
IIgs PC Female Dsub
Mini-Din 8 Dsub-25F or Dsub-9F Dsub Signal
3 3 2 RXD
5 2 3 TXD
4,8 7 5 GND
2 4 7 RTS
1 5,6,8 1,6,8 CTS, DSR, DCD
7 20 4 DTR
----------------------------
007- What is the maximum length for a computer-to-computer
NULL modem hardware-handshaking connection?
Most texts agree that around 50 feet is the 'safe' maximum length.
----------------------------
008- What are the connections for a standard modem cable?
The standard modem cable which can support hardware handshaking connects
eight lines between two male Dsub25 connectors:
Seial Port Modem Signal Name
Dsub25m Dsub25m
2 -------- 2 TD (transmit data)
3 -------- 3 RD (receive data)
4 -------- 4 RTS (ready to send)
5 -------- 5 CTS (clear to send)
6 -------- 6 DSR (data set ready)
7 -------- 7 GND (ground)
8 -------- 8 DCD (data carrier detect)
20 -------- 20 DTR (data terminal ready)
There are many variations depending, mainly, upon differences in Serial
Port sockets; and, some lines may be omitted in some cables.
For NULL modem transfers, the Modem side plugs into the NULL modem connector.

010- What is the maximum modemming speed I can get from my Apple II?
IIe and earlier Apple II's: These require a serial card which usually
plugs into Slot 2. In general, the card determines maximum connection speed for
these computers.
Many early serial cards max out at 9600 baud. Apple's Super Serial Card
(SSC) and compatible serial cards max out at 19,200 baud. (Lightning Systems
made a "Turbo ASB board" add-on for the SSC which extends speed to 230,400. A
1MHz Apple II with the SSC and Turbo ASB should be good for 57.6k baud.)
IIc and IIc+: These machines have built-in serial ports which are
generally compatible with software specified as requiring a Super Serial Card.
Original IIc releases use a cheap method of generating the clock frequency
for the serial ports. Most implementations based on the 6551 chip use a 1.8432
MHz crystal, which gives exact baud rates; but, these IIc's take the master
system clock (14.31818 MHz in an American IIc) and divide it by eight to
produce 1.7898 MHz. The 3% decrease in clock frequency produces a 3% drop in
the baud rate, which is enough to prevent operation with some serial devices,
particularly intelligent modems running at 1200 bps or faster.
This is not always a problem, and I have successfully used one of these
IIc's with a ZyXEL U-1496E modem and a direct connection to a IIgs at 9600 bps.
I have had problems in other cases.
Later motherboards use a crystal, (and, some original motherboards may
have a crystal installed) resulting in much better behaviour. You can make a
reasonable guess at whether you have the original motherboard by checking which
firmware version is installed. From the BASIC prompt enter PRINT PEEK(64447)
and check the displayed value against this list:
255 Original firmware- probably original motherboard
0 UniDisk 3.5 support- may be original or revised motherboard
3 or 4 Memory expansion card- revised motherboard
In theory, the IIc's maximum baud rate is 19,200. Whether it can actually
keep up with that rate is another question. 9600 should be fine. IIc+ baud rate
generation is reliable and max speed is 19,200 baud.
IIgs: Although the firmware IIgs Control Panel allows a top setting of
19,200, maximum speed for the built-in IIgs serial ports is about 230k baud.
Spectrum and a few other telecom products directly control the ports and allow
57.6k transfers.

011- What telecom programs run on Apple II computers?
KERMIT: Available in DOS 3.3 and ProDOS versions, this freeware runs on any
Apple II. (On a GS, you need to turn the "DCD Detect" option OFF in the modem
control panel.) KERMIT is little harder to set up and use than some other
telecom software; but, works fine for Kermit and X-Modem transfers. It supports
VT52, VT100, and dumb terminal emulations.
ZLink: a ProDOS system program that requires a IIe, IIc, or IIgs. It supports
X-modem and Y-modem file transfers; VT100 and partial VT220 emulations. The
"macro" program that comes with it is simple, but fine for some things, like
auto-entering your password. A nice feature is that ALL the options are shown
and set in a single screen display, reached by pressing Open-Apple-?. I used
this program quite happily for a number of years, so it is probably worth a
download to see if it meets your needs.
Talk is Cheap 4.0: An excellent program for the IIe, IIc, or IIgs. It requires
an accelerator chip (e.g. a Zip Chip) in a IIe or IIc to communicate over 4800
baud. With the accelerator chip, you're fine up to 19,200 baud. It has an
excellent scripting language, which was used as the basis for Spectrum's
scripting language. File transfer protocols are X-modem (various types, such as
4K X-modem and 1K X-modem) and Y-modem (for downloads). The manual is a good
tutorial for telecommunications. You may be able to find an early shareware
version on the net.
ProTerm 3.1: This has been the most popular commercial telecom program
available for the Apple II. The program supports many emulations, every file
transfer protocol I know (including Kermit), and if you have a mouse, it'll
give a mouse and pull-down- menus environment.
Telcom: Similar to ZLink in features (except no macros), this is a free
never-finished commercial product by Jawaid Bazyar for IIgs only. Featuring a
mouse-and-menus interface implemented on the text screen, Telcom offers X-modem
uploads and downloads, Y-modem downloads, and VT100 or ProTerm Special Extended
terminal emulations.
Spectrum: This is the ONLY GS/OS telecom desktop program (i.e., standard menus,
the system clipboard for cutting and pasting, etc.). VERY strong scripting
language that even supports sounds, icons, fonts, colours, clickable buttons
(like HyperCard). It supports most terminal emulations, many file transfer
protocols (e.g. Z-modem, though not Kermit. Yet). The author and publisher have
released version 2.0 and are committed to developing it further.
ANSITerm: from Parkhurst Micro Products. Paul Parkhurst's program is supposedly
the best colour ANSI graphics available on a GS. It supports macros, many file
transfer protocols, and there is a demo version to try out. GS users only.

From: Rubywand
Another very good program is Modem MGR from MGR Software. It runs on any
Apple II and works with a wide range of modems, 80-column boards, and clock
cards. MM supports popular protocols from X-modem through Z-modem and many
terminal emulations.
----------------------------
From: Supertimer
Agate offers Z-modem. Z-modem is a much better protocol, with a resume
function (web browsers should take note) and powerful CRC-32 error checking.
Agate was shareware, but the user decided he couldn't accept money for an
unfinished product. None of the shareware checks were cashed. I think it is
freeware now.

013- What are the settings for the Apple Super Serial Card?
Here is some information about Super Serial Card (SSC) Settings:
Recomended Slots
Slot 1 for printer use
Slot 2 for modem (and most non-printer serial communications) use
Jumper Block- configures serial I/O lines. This does not set the operating mode
of the card. Operating mode is set via the DIP switches.
For typical printer use, label is right side up (arrow points DOWN), DIPs
are set for printer operation, and a printer cable is used. This jumper setting
can also be used with a modem cable to make a NULL modem connection to another
computer. (DIPs would then be set for modem operation.)
For typical modem use, the label is upside down (arrow points UP), DIPs are
set for modem mode, and a modem cable goes to the modem. To make a NULL modem
connection to another computer, use a modem cable + NULL modem adapter.
Note that RS-232-C signals on the SSC use negative-true logic; that is, they
are true at 0v and false at +5 volts.
DIP Switch Settings (up is ON for each switch)
These set the default operation of the SSC. The settings may be overridden
via commands entered from the keyboard or from software.
