Thanks for the replies all. This was very helpful. To clarify I was building some firewalls and didn’t have ssh running, a monitor/keyboard onsite, or install media. Disabling the serial port in the bios works though.

Many possibilities: - You ssh into the machine - You just wait until booting has ended and the other ttys are started - You boot the system from an external medium and edit boot.conf - You type blindly (hoping that sending characters still works) - You remove the serial port from your box (BIOS/EFI, PCI-Card) so that it is not discovered and /boot wont switch to it ... Or add an IMPI/iLO/etc "serial" port and make it become com0 - You reinstall the system ... from your backups (I guess you have them at hand, right? ;-) And finally there is one possibility left. But you probably don't want to go into that. It is not for the faint hearted. - Go buy yourself a new serial cable Cheers David
