Serial port using hpcmips

I have a mobilepro 770 which has a functioning serial port (at least
it works in Windows CE).  I have NetBSD 5.0.2 hpcmips installed on it.
 I am interested in using the serial port to control relays on a robot
but can't seem to get the serial port configured.

I looked it /etc/ttys and noticed this file is abbreviated in hpcmips
when compared to i386.

I ran dmesg and didn't see anything that looked like the serial port.

Any help would be greatly appreciated.

You should post the dmesg. If you built a custom kernel, you should
post the config for it as well.

You might need to uncomment something related to serial ports and
build a kernel to get the serial port.

If you using pbsdboot.exe, 
Please check "serial port on" checks on pbsdboot menu.
and you will find com0 on dmesg.

thanx for using hpcmips!

Re: Serial port using hpcmips

Thanks!

That worked.  I'm able to access the serial port and have been able to
get voltage output from it!
