   I have a "black box" I picked up at a yard sale for a buck.  It's about
   1"x3"x6", manufacturer: Hayes Microcomputer Products inc. and labeled:
   microcoupler....off hook.  It has an RJ14 jack (4 wires), and a din 10 plug 
   with a 5inch multicolor riboncable terminating in a db25 (mounted in a box
   .75"x.75"x2.5" with flanges that look like they should fit a pc card opening.)

The Microcoupler was used with 300 baud modems Hayes made for the Apple II
and the S100 bus.

It is a DAA (data access arangement), a holdover from the days when you
couldn't connect just anything to your phone line.  It is basically just
a telephone line interface.  As someone else suggested, it will allow you
to take the phone on and off hook (which can also be used for pulse dialing).

I believe it also contains the 2 to 4 wire hybrid, so it has audio in
and out for a separate modem.  It may also give a ring indication.
