I currently run a Telebit T2500 on a serial port locked at 19200 with RTS/CTS under SCO Xenix 2.3.2. SCO, and other vendors, apparently have a problem implementing HW handshake properly ! I have installed the update from SCO that supposedly "fixes" the problem. After some testing and several transmissions I ran uutraf to check my stats and I noticed that the rates out of my system were twice that of those coming into my system ! Is uutraf screwing up the calculation ? Or is RTS support broken ? The CTS light goes off and on during transmision but the RTS light never goes off when I receive files. Yet the rates with 2400 baud connections are in the 125 cps range while the rates coming in from the same modem are in the 230 cps range. I probably shouldn't trust uutraf but I also heard that SCO hadnt properly implemented the RTS/CTS handshake in there "fix". So the stats got me to wondering. So... I decided to try software handshake with XON/XOFF but no luck. When I try uucp with the modem set for XON/XOFF uucico times out and I get the alarm messages ( uutry output ) and the transfer fails. Is there a way to use XON/XOFF with uucp ? BTW, RTS/CTS is completely broken in SCO UNIX ! I learned that first hand helping a friend with a Telebit under ODT. The people at SCO tech support admit it and have no plans to fix it. It is still broken in their latest release of Unix as well !!! 8-( Jeez. Do they assume that everyone runs 2400 baud modems ?? Sigh... Time to run fas or get an intelligent card I guess. (no.. vendor changes are not an option at this point but I know that's what you were thinking ! 8-) ) Thanks in advance for comments or pointers.
