I've interfaced my PSIM both to the SpeakJet and with MIDI in and
out, both of which are serial interfaces using J3 and J5.  It would
be quite easy to add RS-232 drivers to either of these connectors. 
J5 would be better since the serial communications is done in
hardware.  My PSIM Template code in the code fragments folder already
have the serial input and output code.  You would just have to change
the baud rate from MIDI to whatever baud rate you wanted.

I actually designed the reverse of this.  I wanted to be able to
interface my SpeakJet to the PC.  I made a simple adapter cable to
convert RS-232 to current levels so I can plug an RS-232 cable into
the MIDI in port.  I just needed to change the baud rate.  I don't
have any hardware flow control but don't need any due to the design
of the buffers and rates.  This RS-232 code is in the SpeakJet
folder.  You could easily build the opposite to convert the current
levels into RS-232 voltages to drive RS-232 from the MIDI out port.
