I posted to this newsgroup a little while back, 
concerning a serial port which was sucking 20mA
and refused to loopback.

The problem was the 2632 RS-422 chip, one section
of which worked, but drew too much current while doing so.

Thanks to Ed Satterthwait of DEC for help in locating
and fixing the problem.
