A) n8r? Perhaps that r should be a 1? B) Can you set the console twice like that? > However I have seen that if I don't open the serial port from another machine, I can't reboot or boot kernel, as the output seems to freeze until port is open.

It sounds like the serial port is waiting for a signal, like DCD, to become active before proceeding. I believe this has been discussed before, have you checked the linux-kernel mailing archive? Use google to find it. ..Stu -- We make multiport serial boards. (800) 426-8979
