LILO: image = /boot/vmlinuz_2419 root = /dev/hda3 label = linux_2419 append="console=ttyS0,115200n8r console=tty0 vga=0x0301" 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. When I open the serial port, normal operation is resumed. Is there something to solve this issue? I would like to use the serial console only when needed not always that I want boot or reboot machine. Regards, Carlos Velasco ^ permalink raw reply [flat|nested] 2+ messages in thread

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. <http://www.connecttech.com> (800) 426-8979 ^ permalink raw reply [flat|nested] 2+ messages in thread
