This file lists changes to Chat.
Last updated 2/13/1993
Version 0.5
This version was the first public release of Chat. It was intended as an
extended beta program, and had a limited feature set and a rather clunky
editor.
Version 0.9
This is the second public release of Chat. There have been numerous
changes, as listed below:
Chat now allows monitoring multiple channels simultaneously.
43/50 line mode is now supported on EGA/VGA cards.
The editor has been greatly improved, and now features automatic
word-wrapping.
Private messages may be sent between chat users.
A list of chat users is now available.
The communications routines are more reliable than in previous
releases.
The help has been expanded greatly.
The documentation is greatlty improved (believe it or not!)
Mouse support is more consistent.
Known bugs:
Chat uses Novell's IPX protocol for sending messages between
systems. This protocol does not guarantee that messages will be
delivered. I have never personally seen a packet fail to be
delivered in this program, but it is possible. This could result in
messages not being sent, or the user list being incomplete. Unless
your network is particularly flaky, however, I doubt you will ever
see a missed packet.
Chat has a limited number of buffers for handling cummunications. If
a large number of users are logged on to chat, it is possible that
packets will be dropped, resulting in symptoms like the above.
Again, I have never seen this problem arise in practice, but Chat
has not been extensively tested with more than ten users. However,
if you have slow workstations or a large number of users, you may
experience lost messages.
The program does not handle low memory conditions very well. If Chat
runs out of memory, it will display a message explaining that it has
run out, and quit immediately. It requires approximately 300K to run
in initially.
Planned features:
There are two features planned for the next release of Chat:
Private channels:
The next release will allow users to open private channels. Only
invited users may enter these channels. You can thus have
private discussions without worrying about "lurkers"
eavesdropping.
Configurability:
The next release will be somewhat more configurable,
particularly the communications system.
