1200 BPS DCM-212 Modem (260-1385A)  Switche Settings   Faxback Doc. # 7054

DIP switches control the DCM-212's power-up conditions. These switches must
be set before you turn on the power.

Use the DIP switches to select either the Tandy or Hayes protocol.
Generally, some switches are only needed in one mode or the other. However,
there are some switches that are common to both modem protocols.

**On is down or towards the numbers on the switch.
 
The following table shows the DIP switches and their functions:
