Greetings! I have FreeBSD 4.6.2-RELEASE running on a rackmount chassis, and
I want to convert it to a headless box, with all console output redirected
to the serial port. I have followed the directions in the FreeBSD handbook
as follows:

In my kernel, I have the flag 0x10 set on serial port 1 to make it a
console:

device          sio0    at isa? port IO_COM1 flags 0x10 irq 4


In my /boot.config file, I have the "-P" option set to probe for keyboard on
booting, and then redirect the console appropriately.

Now when I go to reboot the machine (with the keyboard removed), I see the
following on my dumb terminal on the serial port

/boot.config: -P
Keyboard: no

I then get the message saying "Press [ENTER] to boot kernel or any other key
to enter single user mode". I press enter, then I see:

Booting kernel...

I then do not get any more display on the serial port, and there is no
display on the monitor, either. However, the box boots fine and I can get
into it via telnet. The problem is I lost my console display on both the
serial port and the monitor. Any idea why it stopped displaying to the
serial port after leaving the boot loader and starting to boot the kernel?
Thanks!
