I excerpted this from a huge (178 block) acos help file...
I know the PSE stuff works, because I do pse programming, but I
don't know about the DataMedia 1500, vt100 or vt52...
--------------8<------------------8<--------------8<---------
o Datamedia 1500
This emulation is more or less the standard in the Apple II world since both
AscII Express and ProTERM (the two most popular terminal programs) fully use
the entire command set of this emulation with no flaws whatsoever. AE boots
up ready-to-rock in this mode; with ProTERM simply set your emulation in the
dialer or via your online parms. Most other terminal programs for the IIs
also support this emulation, so if you want to go with something *EVERYBODY*
in the Apple II world can enjoy, go with this.
Control-H 8 - Cursor Left <arrow key> As you will also find below with
Control-J 10 - Cursor Down <arrow key> ProTERM Special, DataM uses many
of the same control codes so you
Control-I 9 - Jump to TAB spot can easily move up to PTS later,
All emulations just about support
once you have exploited DataM to
the TAB function, so I won't show its fullest.it below, but it still works.
Control-L 12 - Clear Screen All the codes in DataM excluding
Control-Y are compatible w/ PTS,
Control-Y 25 - Home Position so I suggest using DataM in very
Control-^ 30 - Direct Cursor Positionin liberal amounts and save PTS for
chr$(30) chr$(x+32) chr$(y+32) the more detailed areas where ya
could have "two" of everything,
Control-O 14 - Inverse OFF one for PTS users only, and one
Control-N 15 - Inverse ON for everyone else, where "every-
one else" includes just about da
entire modem population since these control codes generate very few bad effects
on other term programs which don't support DataM seeing as most filter out ctrl
codes anyway. The arrow keys are commonly found on most straight ASCII terms,
and so is TAB and the clear screen. Inverse ON and OFF tend to generate funny
little characters such as musical notes and whatnot on IBM terminals, but that
isn't such a big deal since it doesn't "ruin" the look, usually.
o ProTERM Special
This emulation is supported only by the terminal program ProTERM at the time
of this writting. That's bad in a way, since it's not as common as DataM but
ProTERM *is* widely used by many Apple II owners, so there IS a "market" for
this emulation. Like DataM, this is a mainly Apple II Only emulation, mainly
because there's only one program which supports it... But, unlike DataM, you
can do very VERY fancy things with PTS which could never be done with DataM,
mainly the music and mousetext. Of course, because of the mousetext, anyone
who is using ProTERM Special must also be using an Enhanced Apple II such as
an Apple IIc, IIgs, or IIe with the newer ROMs and 65c02.
Control-E 5 - ID Code, Returns: "Control-]", 29
Control-H 8 - Cursor Left <arrow key>
Control-U 21 - Cursor Right <arrow key>
Control-J 10 - Cursor Down <arrow key>
Control-K 11 - Cursor Up <arrow key>
Control-D 4 - Delete Character Under Cursor, Pull Line to Left - no scroll
Control-F 6 - Insert Spacebar Under Cursor, Push Line to Right - no scroll
Control-L 12 - Clear Screen
Control-W 23 - Clear from Cursor to End of Screen
Control-Y 25 - Clear from Cursor to End of Line
Control-X 24 - Home Position
Control-A 1 - Jump to Column #1
Control-B 2 - Jump to Column #79
Control-^ 30 - Direct Cursor Positioning
chr$(30) chr$(x+32) chr$(y+32)
Control-V 22 - Insert Line, Scroll Down
Control-Z 26 - Delete Line, Scroll Up
Control-O 14 - Inverse/MouseText OFF
Control-N 15 - Inverse ON
Control-P 16 - MouseText ON
Control-R 18 - Repeat Character
chr$(18) chr$(char) chr$(repeat)
Control-T 20 - Tone Generator
chr$(20) chr$(tone1) chr$(tone2) chr$(duration)
Right now, this is the big "gimic" of many Apple systems across the nation.
Everybody and their uncle seem to be getting into ProTERM Special, and alot
of it has become very competitive. If you would like to see ProTERM Special
at it's "best" I'd suggest you call one of the ProTALK systems in the area,
such as The Nuclear Escape, (215) 540-9811. ProTALK is a rewritten GBBS in
many ways, and still runs under ACOS of course. The author, Parik Rao, has
spent many hours thinking up and writting some of the best uses for PTS and
if you've never seen PTS before, you really should call the Escape.
o DEC VT-52
This emulation is among one of the most popular every developed. Many many
terminal programs for just about every computer produced support DEC VT-52,
which is rather limiting but still powerful. I don't have the complete list
of ESCape codes for this emulation at this time, but I promise many more in
later releases of these files. Of course, VT-52 is also OLD and is already
just about completely replaced with VT-100 but it IS still around so I have
included it here. If you want a comprimise between DataM which is Apple II
only more or less, and something
ESC Z ID Code, Returns: "ESC/Z", 27 47 90 which other folk can enjoy, this
could be it. ProTERM supports it
ESC A Cursor Up - no scroll with no prob and I believe AscII
ESC B Cursor Down - no scroll Express also can use it, plus of
ESC C Cursor Right - no scroll course, all the IBM folk who can
ESC D Cursor Left - no scroll enjoy it and all those Commodore
folk with REAL terms and whatnot
ESC I Cursor Up, With Scroll so this just may be The Thing!
ESC H Home Position
ESC Y Direct Cursor Positioning
chr$(27) chr$(89) chr$(x+32) chr$(y+32)
ESC J Clear from Cursor to End of Screen
ESC K Clear from Cursor to End of Line
o DEC VT-100
This emulation is incredibly common in the MS-DOS world, and many Apple and
other computers, have terminal programs which support this emulation, which
is by far the most powerful one listed in this file. ProTERM Special could
give it a run for it's money with the MouseText and Tones, but DEC VT-100
is much more powerful even without the tones and I believe there is an ANSI
subset of VT-100 which allows color graphics and tones(?) among other items
but I have yet to see an Apple II term supporting ANSI, since the Apple II
80 column text screen can't handle color and whatnot. Listed below are alot
of the ESCape codes found in VT100, but this list is far from complete...
ESC Z ID Code, Returns: "ESC[?", 27 91 63
ESC [#A Cursor Up - no scroll
ESC [#B Cursor Down - no scroll
ESC [#C Cursor Right - no scroll
ESC [#D Cursor Left - no scroll
ESC [#;#H Direct Cursor Positioning X;Y
ESC [#;#f Direct Cursor Positioning X;Y
ESC [E New Line (sorta like carriage return)
ESC [7 Store Cursor & Attributes
ESC [8 Recall Cursor & Attributes
ESC [m All Attributes Off You can link these together
ESC [0m All Attributes Off with semi-colons, like many
ESC [1m Bold Face ON of the other ESCape codes.
ESC [4m Underscore ON
ESC [5m Blink ON Ie: ESC [5;7m
ESC [7m Inverse ON Blink & Inverse ON
ESC [K Clear from Cursor to End of Line
ESC [0K Clear from Cursor to End of Line
ESC [1K Clear from Cursor to Start of Line
ESC [2K Clear entire Line
ESC [J Clear from Cursor to End of Screen
ESC [0J Clear from Cursor to End of Screen
ESC [1J Clear from Cursor to Start of Screen
ESC [2J Clear Screen
ESC [#r Set Top Of "Window"
ESC [#;#r Set "Window" size from line # to line #
ESC H Set TAB Spot at current column
ESC [g Clear TAB at current column
ESC [0g Clear TAB at current column
ESC [3g Clear All TAB Spots
ESC [6n Get Cursor Position, Returns: "ESC#;#R" X;Y
The "#" in all of the above statements refers to a number, a true ASCII
numeral. Meaning, when you go ESC[2J to clear the screen, you're sending
exactly that, ESCape, "[", "2", and lastly, "J". This is different from
all of the above emulations where you would send say, Control-B to do one
of them "2"s since the ASCII value of Control-B is 2 but it is NOT in any
way similiar to the number 2, which is really ASCII value 50! The direct
cursor positioning works in the same way, you send "22", two ASCII 50s,
to say "22" while in the above emulations you would simply send Control-V
to show a 22. This makes VT-100 a little slower but it's alot easier to
program because you can do PRINT statements litteraly as seen below...
PRINT CHR$(27) "[2;20R"; That one line would set the "window" size
from line 2 to line 20 on your monitor...
VT100 is, when you really get into, incredibly powerful. If you would like
to see an Apple system running under ACOS using VT100, call any one of the
Midway systems, such as The Midnight Tavern at (215) 540-0695 3/12/24 30meg
and you'll get a nice show. Of course, ALOT of MS-DOS BBS programs support
VT100 and the ANSI graphics and whatnot, but I wrote this file for Apple II
folks and such...since we're "just walking into" this realm...Enjoy!

Is that a good enough response for ya?
