I have setup a system with serial console and when running the following command when there is no serial cable connected: reboot The system is not rebooted. It seems to be waiting for the getty to die. Killing the getty continues the reboot process. I have the following in my /etc/inittab: # Serial console S2:12345:respawn:/sbin/getty ttyS0 9600 vt100 any my kernel is booted with arguments: console=tty0 console=ttyS0 Not sure what is the cause of this problem. Thanks.
I looked a bit into this. This only happens if serial console is the primary console (the last definition). Using 9600 in getty is bad. See /etc/gettydefs. CRTSCTS flow control is being used. This isn't usually what you want with serial consoles. Switch to DT9600 (Dumb Terminal) to get this to work properly. Still an "issue" in Rawhide as of 19 Jul 2000.
