Some people using OS/2, Win95 (when someday somebody will force me
to install Win95 I'll do this on separate HDD and my real HDD will be
hidden 10 meters under the ground - with Win95 everything is possible ;)
...so those people can write something to support functions built in
their systems. I'll stay on DOS for now ;) although I know it's suicide ;)

Hmm, ask him... but I have almost written AX.25..... ;( Anyway ask...

Hmm, yes. One reads frames, decodes them and puts data into some kind of
buffer. The second one can be common for all AX.25 (and not only)
connections. It decreases timers (like T1, T2) and (re)transmits data when
one of them reaches 0.
I (or somebody) have to add signals to my kernel - as it is poor without
them. Because now adding too many processes makes everything very slow
(there's no WAIT or SUSPENDED state - everything is RUNNING).
For example: first process is keyboard input interpretation;
after attaching loopback there is process to interpret data incoming from
this interface and another one to retransmit frames if necessary;
when you connect to yourself you have process called "Outgoing session"
and "BBS user: SQ6BOT". And five processes without WAIT state aren't
working fast...

Maybe 10kB 7+ file is unable to get through some links ?! I'll send it again
soon in 5kB pieces.

It's almost ready. I have to finish AX.25 interpretation (this loopback
looks as an AX.25 link). Now it has no T1/T2 timers and no retransmission
(as it's only loopback) and you can connect through loopback to yourself
(ie. to BBS) and it is beginning to interpret your commands (now only '?'
works ;-). I hope I'll complete whole AX.25 before my parents will lead me
to psychiatrist ;-)))) They are very scared why I didn't leave my room
since last two days except for coffee and piece of bread... >8-]

I can't stand when I'm always typing "if(x=0){" and not "if(x==0){".
Try to guess language ;-) Fortunately compiler always warns me...
