according to the manual here, there are two banks of dip switches on the
board, S402 and S401.  S401 seems to be the baud rate.

mode			switches
			0 1 2 3 4 5 6 7
9600 baud		0 0 1 1
no parity		        0
even parity                    0
normal parity                    0
full duplex                                               1

150            0 1 0 0
300            1 1 0 0
600            0 0 1 0
1200           1 0 1 0
1800           0 1 1 0
2000           1 1 1 0
2400           0 0 0 1
3600           1 0 0 1
4800           0 1 0 1
7200           1 1 0 1
9600           0 0 1 1



You could also throw it into local mode and type
the appropriate escape sequence:
