	First, let me say thanks for the information...I have been able
to use the serial port as console.

	The relevant switch was on the card that has the serial/hpib/hil/
audio/lan, etc. On my machine, the cpu is on a separate board. It was
the switchbank labeled 'HPIB/rs232', the switch itself is labeled 'REM'

	I got it to work with a standard 'pc' mapping of a db9 to db25,
but some of the control signals seem strange. At least their behaviour
on my traffic light was not normal. If you could find out how your HP
adaptron maps, it might be useful information...
