AFAIK, there is no support or driver for this port. I looked at it too
since I have a SCSI adapter with a Parallel port.

How about using a small adapter, say a 25 pin connector wired to another
25 pin connector in between the support modem and the remote console
port. Connect a line to one of the handshake lines and monitor power
there. It won't interfere with the modem function and you'll be able to
see when power goes off.
