Re: Forcing a serial console for the kernel

[buhrow%lothlorien.nfbcal.org@localhost (Brian Buhrow)]

        Hello.  You're correct.  Any kernel that has serial support in it,
i.e. device com* at something, will be able to use any of those serial
devices as console assuming the bios sets the device up at boot time, and
you can tell the boot loader to use that device as a serial console.  I use
serial consoles all over the place, and I never use the kernel options for
getting those serial consoles pointed at the devices I want.
