I would also like any information that is available on line disciplines;
I've been poking through the serial line drivers in the Xenix kernel using
a debugger and it seems like SCO Xenix only supports one line discipline.
Am I missing something obvious ?

Thanks to all of you who responded to my question about SLIP, those answers
have given me the correct solution, ie. line disciplines, now all I need to
do is implement it.

While I'm on the subject, why is there is SLIP code for BSD 4.3, 4.2 and
SUN OS but none for SysV ? Is it that AT&T wants everyone to use UUCP so that
their phone bills will pay for future development projects ?

Bill
