    Even when I disable com1(3F8 irq4) in the bios
    OpenBSD detects it, but it wont input/output anything
    I already tried "set tty com0" and hooking my terminal to com2

    What I need is a shell listening on com2 (2F8 irq3, openbsd's com1)

    Try "set tty com0" in boot.conf, because it's the first functionally com
    which is found by kernel when the first is missing/disabled :-).

    Hi,
      Im am trying to setup a serial console on
    an i386 openbsd box. The Com1 (3F8 irq4) is defective
    on the machine, so it is disabled.
    The com2 (2F8 irq3) works great, I tested it connecting to
    a sparc serial console.

    So I added "set tty com1" in /etc/boot.conf
    and I enabled the console in /etc/ttys :
    console "/usr/libexec/getty std.9600" vt220 on insecure

    I dont really cares if the kernel boot messages doesnt appear
    on the serial port, I just want a shell to listen there

    When I boot the OpenBSD box with a terminal hooked to it,
    I get the very first line after the boot prompt, something
    like "loading /bsd 283948+23425" I dont remember exactly,
    then the output stops, But I am able to type..

    Is it possible to use com1 ?
