That is interesting because I just spoke with Chris in SCO support and he claims that 19200 baud is broken no matter what you do and RTSFLOW CTSFLOW do not work correctly. Here is what happens on my machine: 1) Modem answers the phone. 2) Modem raises DCD. 3) uugetty is now able to open the port and apply the stty settings to the port. If RTSFLOW and CTSFLOW are specified in the gettydefs file, the computer promptly drops RTS, and the modem cannot send any data to the computer since the modem is waiting for an active RTS. 4) If I do not specify RTSFLOW/CTSFLOW in the gettydefs file, the computer will hold RTS high. I am really glad that it is working for you, but SCO claims that it is broken, and it is broken on my machine. I am using SCO's drivers for a DigiBoard Com/4 dumb serial card. SCO support claims there will be a support level supplement for the 19200 problem, but the RTS/CTS problem will not be fixed until 3.2.2 or so. BTW: What serial board are you using and what does your gettydefs entry look like? -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry
