I have a problem and a general question. problem: I have a serial port driver which works fine with modems. I can make PPP connections and all is well. The problem is "cu". The first time I run cu on a callout port it runs fine. When I quit it drops DTR and exits normally. Next time I start cu on the same port it just hangs until I either turn off the modem and turn it back on or remove the port cable from the modem for a second. Everything then works fine. It starts taking at commands and ~. to quit. I can enter cu again and it will work. Just that each time I quit I have to turn off the modem. What remains hanging when the driver closes the port to cause this problem?? general question: How can you set tty speed for 64K bits/sec or 56K bits/sec for data transfer over ISDN?? Thanks amir
