I had a strange one the other day. Using Alphacom over a serial line to a SCO machine and the only way it would work was if the emulation was VT100.
Details: I could attach an old Wyse60 terminal to the same line and it worked fine no matter what emulation was chosen. With the PC, however, even changing emulation after logging in, with or without a tset, would send the screen insane - looked to me like the baud rate had suddenly changed. I found that I could still type commands, and doing an stty -a redirected to some file showed that nothing had changed on the Unix side (as expected). I was blaming a bad download of Alphacom, but then I tried regular old Windows Hyperterminal; this looked like it was having communication trouble: dropping characters, some characters set to high bit, etc. I cut the wiring to its basics (2,3,7) but no change.
So my assumption was and is a bad serial card - but why would vt100 work? I could even do long ls -lR's without a glitch.. this has me puzzled.
Got something to add? Send me email.
