MultiTech MT2834 MultiModem II

This is how I set the DIP switches:
DIP switches
The modem init string I used was:
S7=45 S0=0 L1 V1 X4 &c1 E1 q0 m1

For help, type ATH1 or ATH2 or ATH3

To return the AT&F command to read factory installed defaults, enter AT&F8&W0.

The MultiTech web page is at The dip switch settings for the 2834 BA are documented at
