Has anyone out there in netland ever tried to get an internal everex 920 (hayes 1200 baud) modem running with xenix ??? The problem is that always the message 'loose cable ....' appears when the phone rings the first time. I tried out setting 'ATS0=2\r' by ioctl from a 'c' program and by '( stty 1200; echo "ATS0=2\r" ) > /dev/tty2a 0<&1' from the shell. The getty dies very fast (for shure), even disable - set - enable does not help. When putting the shell setup into /etc/rc (before the getties are forked) it sometimes works (mostly when it does not need to work). The getty I described above is put on /dev/tty2A with the standard B1200, HUPCL, OPOST, CR1, ECHOE, NL1 setting. I think the problem is a more technical one. Here in Germany the phone rings sometimes twice the first time. So I think the DCD is also set and reset quiet fast everytime the modem sends RING. This will hang the getty. Even setting 'ATQ1' to disable the RING does not help. I think it does not turn of the DCD. Have to test it with the scope. Does anyone know how to get the getty more tolerant with fast switching DCD ???? Thanks in advance, dirk :-) ...!unido!altger!dirk
