I have a EST/SBC8260 board (also made by EST before they were bought by 
WR, many years ago) that also uses RJ-11s for serial I/O.  Odds are good 
they have the same pinout:

1 MAX-232 Rin
2 MAX-232 Tout
3 n/c
4 Ground

If you ohm-out the pins to find ground and then use a scope as you power 
on the board to look at the pins to find Tx, you have most of the puzzle 
solved.
