My Xenix 286 system that I use as a mail/news server cannot sustain 9600 baud data transfers with uucp and completely fails at 19200 baud. If I enable rtsflow and ctsflow, the problem should go away...??... The '286 (Xenix 2.2.3) system is directly connected to a '386 running Xenix 2.2.3 and also to a VenTel (like TeleBit) modem. I "think" that RTS/CTS flow control is broken in the sense that I can never see the RTS line toggle (however CTS from the modem does) when connected to a breakout box. Maybe I should re-RTFM yet again.... RTS/CTS flow control to the VenTel modem seems inoperative in spite of the fact that dialTBIT specifically enables flow control with an ioctl() call. The VenTel has it's registers set for rts/cts (as set up with "dialTBIT -z"). If I directly connect two computers with a cable, I can set rtsflow and ctsflow in the gettydefs file of the called computer, however I cannot figure out how to set rtsflow/ctsflow on the calling computer when I attempt a uucp login. Are the some undocumented options in the various L* files that allow you to set up the out-bound stty options for a DIRect call?? If I upgrade to Xenix 2.3.*, will RTS/CTS flow problems go away??? The hardware I am using is an 8Mhz AT clone and an Intel 16Mhz 386 system. All uarts are 16550's. For the directly connected computers, the null modem is wired for rts/cts, dsr/dtr hand-shake. Thanks, tony...
