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.
