According to Jim Bryant:
> how do you configure the comconsole on /dev/ttyd2 ???
You go to /sys/i386/boot/biosboot and read README.serial.
It has the following in it...
- Using a port other than COM1 as the console requires some recompiling.
Again, it's usually assumed that COM1 will be available for use as a
console device on a dedicated file/compute/terminal server, so hopefully
you'll never need to do this. But if you feel you must change the console
to a different port, here's how:
o Get the kernel source package.
o Edit /etc/make.conf and set BOOT_COMCONSOLE_PORT to the
address of the port you want to use (0x3F8, 0x2F8, 0x3E8 or
0x2E8). Only COM1 through COM4 can be used; multiport serial
cards will not work. No interrupt setting is needed.
o Create a custom kernel configuration file and add appropriate
`flags' for the serial port you want to use. For example, if you
want to make COM2 the console:
device sio1 at isa? port "IO_COM2" tty flags 0x10 irq 3 vector siointr
The console flags for the other serial ports should not be set.
o Recompile both the boot blocks and the kernel.
o Install the boot blocks with the disklabel command and boot
from the new kernel.
