port-pmax: Using mouse and keyboard ports as RS232

I need an extra (low-speed) serial port on a DECstation 3100 and
5000/200.  On the NetBSD pmax page (under the 2100 and 3100) is the
comment: "Two ports are reserved for a keyboard and mouse. (An
adaption-connector can make these ports usable as RS-232  serial ports
with no modem control.)"

Can anyone give me a part number, or wiring information for such an
adaptor?  Any advice
would be appreciated.
