I'm running SCO Xenix 2.2.1 on an IBM AT (8MHz) with a Hayes 2400 V series modem. I've noticed some pretty poor performance with uucp at 2400 baud, namely about 160 cps. At 1200 I'm getting about 110 cps though. The modem is hung off an IBM 0-12meg card, which has serial and parallel ports on the card. Shouldn't I be getting about 220 cps or so ? This has been the case with every system I talk to, not just one. I have noticed *very* occasional spurts up to about 180 cps, and sometimes down to about 120 cps. I want my 220 cps ....... -- Dean Carpenter ...{bigtex|texbell}!rpp386!bunyip!deano (preferred) ...cs.utexas.edu:ibmchs!auschs!deano.austin.ibm.com!deano (sometimes sporadic)

You have to set your windows to seven instead of three, which is default.

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) --- Message-ID: <1329@rrzbu.UUCP> Date: 29 Aug 89 13:23:49 GMT ... standard uucico: Address before after Offset: 19522 Address: 63:19362/3 0x3b0 0xnnb0 Entsprechend fuer den uucico aus dem International Supplement R1.0: (appropriate for the ... ) Offset: 19628 Address: 63:19468/9 0x3b0 0xnnb0 ...

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 -- Klaus Kleemann ][ ampr : db2hk@db0hb.ampr.org TU-Hamburg-Harburg, Meerestechnik I ][ privat: klaus@ccsq.UUCP Elbchaussee 35, 2000 Hamburg 50 ][ dienst: klaus@mt1hh.mt1.tu-harburg.de Tel. +49 40 3807-2914 ][ dnet : mt1-kkl@tuhhco.tu-harburg.de -- Klaus Kleemann ][ ampr : db2hk@db0hb.ampr.org TU-Hamburg-Harburg, Meerestechnik I ][ privat: klaus@ccsq.UUCP Elbchaussee 35, 2000 Hamburg 50 ][ dienst: klaus@mt1hh.mt1.tu-harburg.de Tel. +49 40 3807-2914 ][ dnet : mt1-kkl@tuhhco.tu-harburg.de
