Tenex sells a true RS2332 interface (made by Aprotek) for $32.95.
(Aprotek sells it for $39.95!)  It plugs directly into the user port
at one end and it has a cable leading to a male DB25 connector at the
other end.  One nice feature is this device duplicates the user port
so that you can still plug in your current user port accessory without
having to uplug the interface.  It allows you to talk to standard RS232
device like modem or serial printer.
