It's 10 times too complex when all you need/want is a simple serial console setup, but since you unfortunately have removed the old and trusty getty_ps from the distribution...

Fri, 5 Oct 2001 15:45:14 -0700 -----Original Message----- From: rick herbel [mailto:rick.herbel@tccworld.com] Sent: Friday, October 05, 2001 3:38 PM To: 'mgetty@muc.de' Subject: it appears elilab.com is down? When my client hang up the log files show the following errors. I can restart mgetty by using minicom to give it an ATZ and then an init q. How can I cause it to happen without manual intervention? Also every so often mgetty does not use login.conf to init my ppp session instead it uses the default /bin/login ? not consistant. Talking to an external modem. Any ideas would be appreciated :) Rick linux 2.2.16-22 mgetty-sendfax v 1.1.25-5 log Oct 5 14:05:24 comdev mgetty[1723]: TIOCMBIS failed: Input/output error Oct 5 14:05:24 comdev mgetty[1723]: cannot turn off soft carrier: Input/output error Oct 5 14:05:24 comdev mgetty[1723]: tcgetattr failed: Input/output error Oct 5 14:05:24 comdev mgetty[1723]: cannot get TIO: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: TIOCMBIS failed: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: cannot turn off soft carrier: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: tcgetattr failed: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: cannot get TIO: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: mg_init_device failed, exiting: Input/output error Oct 5 14:05:25 comdev mgetty[1723]: cannot get terminal line dev=ttyS0, exiting: Input/output error ... repeats initab S0:2345:respawn:/sbin/mgetty ttyS0 -m '"" ATZ OK"' -D /dev/ttyS0 [root@comdev /root]# /bin/stty -F /dev/ttyS0 -a speed 9600 baud; rows 0; columns 0; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol =
