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)

standard uucico:	Address		before		after

Entsprechend fuer den uucico aus dem International Supplement R1.0:
(appropriate for the   ... )
	Offset:		19628
	Address:	63:19468/9	0x3b0		0xnnb0

...
(offset for lseek/write, address for adb)

	% adb -w uucico
	* $d
	* 63:19362?x
	63.:19362.:	0x3b0
	* 63:19362?w 0x7b0
	* $q

(Don't forget, to backup your original uucp...)

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
