SCO Xenix's standard device driver's RTS/CTS flow control (I'm at revision 2.3.2) _still_ doesn't work properly. They seem to have a) treated CTS as an edge-triggered signal and b) made it share the same flag as is used by XON/XOFF flow control. This causes _serious_ problems when you need both flavours of flow control simultaneously (can you say interactive sessions on a speed buffered modem? I knew you could...) I have used Specialix Systems' SI intelligent serial adaptor, and their drivers do flow control properly. This seems to be an exceptional case :-( -- Eunet: Ronald.Khoo@robobar.Co.Uk Phone: +44 1 991 1142 Fax: +44 1 998 8343 Paper: Robobar Ltd. 22 Wadsworth Road, Perivale, Middx., UB6 7JD ENGLAND. $Header: /usr/ronald/.signature,v 1.2 90/01/26 15:17:15 ronald Exp $ :-)
