I can't find anything about windowsize in the Xenix 2.2.1 manual.
But here's a solution: (I fetched it from a local newsgroup)

I made this patch several months ago without any trouble since yet.
By the way another question:
I want to reduce the timeout delay in case of an uucp-protocol error
due to linedistortions. (Sorry, no MNPx available yet)
After each transmissionerror the line is inactive for over 20
seconds. Does anyone know a similar patch like the above one for
this purpose?
regards, Klaus
