What is COM?
So you type 'irc' at the command prompt hoping to join your favorite channel and
instead find yourself in this strange world where you have to press space to
talk, the commands you expect don't work, and you can't even figure out how to
quit (hint: try 'q'). This is 'COM' (aka, 'COMMODE' or just 'com').
COM is a chat program which is unique to SDF. The original version dates back to
1994 and it has been developed and used on the SDF servers ever since. Together
with the 'bboard' BBS it is one of the primary ways SDF users communicate with
each other. Some features may be familiar to you from other programs, but many
will be new to you. Most notably, COM is command-driven, meaning that you are in
"command mode" by default and must hit a key (spacebar or enter) before you can
talk. See below for additional commands, all of which are simply typed in
from command mode.
So why did you get COM when you expected IRC? For reasons of security and
concerns about abuse, IRC access is not allowed unless you are an ARPA member or
higher. If you are reading this then it is likely you are not. For this reason
when you type 'irc' at the shell, COM will be launched instead. This allows new
users an opportunity to interact with other SDF users and hopefully answer some
of the questions they might have. Unlike IRC, COM is not network-based and only
users who are currently logged into SDF can use it.
Basic rules of etiquette to keep in mind:
* Many people idle in com. You can check idle times with 'I'. If the
room has been quiet for a while, say hello but give people time to
respond. If you have not read the tutorial you may get some coarse
replies, and you might end up here, now, reading this. Welcome. :)
Things not to do:
* Ask how to 'hack'.
* Attempt to use any IRC commands (they won't work and will make you
look foolish).
* Repeat the same question over and over.
Getting started: a walkthrough
COM is based around 'rooms'. The default room you enter when you start the
program is 'lobby', SDF's Welcoming Room.
Type com at the command line to start com. When com starts, you will be placed
in 'lobby'. A list of users will be displayed. You will also be in command mode.
In command mode, all you will see the cursor; there will not be a prompt.
Command mode allows commands to be run such as seeing a list of users.
In command mode, type w to see a list of users, the name of the room you are in,
as well as the topography.
The output will look something like
[you are in 'spacebar' among 1]
wliao@iceland
Now, type l (lower case L) to see a list of rooms. The output will look
something like
room-name # created time topic
--------------------------------------------------------------------------------
spacebar 16 22-Aug-16 08:49:32 there is life out there
lobby 1 09-Sep-16 08:49:13 SDF's Welcoming Room
anonradio 19 09-Sep-16 04:11:06 DJ Kumata!
--------------------------------------------------------------------------------
There seems to be a lot of users in the room "spacebar". Let us join in
on the fun, shall we? Type g and the name of the room to join.
:goto> spacebar
When entering the room, a list of users will be displayed. Now, let us
say hello to the room.
Enter a space to enter input mode. When entering input mode, a prompt
of your user name will appear. Say "hello" to the world and end the
line with an enter key.
[wliao] hello world!
The next thing you'll probably want to know is what people talked about
before you entered so you can join in the chatter. Type r to get a
short 18 line "r"eview of what was said last. If you want more context,
press R. You will se a prompt like this:
:lines>
Just type the number of lines you are interested in and finish with
return; you'll get a scrollable history of said lines length.
When you are ready to quit, type q to leave com. You will see an
Unlinking TTY .. message appear.
FAQ
How do I use backspace in com?
Try - in command mode in com to toggle behavior. Or, use stty or
'bksp' (at the shell prompt) to set the backspace correctly.
How can I be in com multiple times?
The basic rule is to be on a different server when entering com.
Some common ways of doing this is to use screen, run ssh twice,
etc.
How do I send private messages?
Use the s command in command mode: suser@host. Please note the
@host portion; this is a required element of the command. If the
user is in another room, add an optional room parameter to send
the message: suser@host room.
How do I see what happened in the past?
Use the r key to review. Use R followed by a number to control
how many lines of history to review. The p key can be used to
see the history of another room: proomname. The p command can
also take an optional number of lines to display: proomname
number.
How do I see who is in another room?
Use W (upper case w) to see who is in another room.
I see <wliao@iceland DUMPs in 22 characters of 2 words in 3 lines>.
What does that mean?
Use the r or R command.
I see <wliao appears>. How do I do that?
Use the emote command in command mode. Use e followed by the
action at the prompt: :emote> tests this out.
Why do I have to keep pressing the spacebar to talk?
Other keys can be used to enter input mode. Try the h to see
what keys are not being used such as the enter key.
How do I erase a line?
Use ^u (control + u) to erase the line. ^w (control + w) will
erase a word. ^r will re-display the current line.
I accidentally ignored somebody! I didn't mean to do that :(
'i'gnore the same user again to remove from the ignore list.
Why isn't anybody talking?
That's life. Harden up.
COM Commands
Here is a list of commonly used COM Commands. It only covers the basics, so
refer to the online help (with 'h') or man page for more infomation. Some of
the commands will not be available to pre-validated users.
* e - emote
* g - goto a room
* h - command help
* I - user idle query
* l - (lowercase L) list open rooms
* L - post a link to com
* p - peek into room
* q - quit commode
* r - room history
* R - extended history
* s - send private
* w - (lower case w) who is in the current room
* W - (upper case w) who is in a different room
* - - (hyphen) key in command mode will fix your backspace (use this
if your backspace keeps showing up as ^h or ^?)
* + - tell you utc
* U - (capital u) will tell you how long other users have been
members and if they are ARPA or Meta-can-validate you
Note: Although you type 'com' to start com, the man page is accessed with 'man
commode'
