Am at work and can't see which box I have, but it's probably close in
model number to yours....

OK, this is what I did to slap something together *quickly* to test it
out.  I got a 9pin serial extention cable, cut one end off, got an old
phone cord, cut one end off, stripped wires and solders as below:

Serial Pins     RJ-11 Pins
-----------     ----------
     5              1
     2              2
     3              4

To find which wire is which, I used a circuit tester--took a minute or so.
 Of course, if you don't have a tester, it's a little harder :)  If you
need the actual COLORS, I can tell you tonight when I get home (if I still
have my crib sheet laying around).  I *think* the color codes are
standard.

Let me know if that helps.
