Multi-Tech Systems MT2834BLR ユーザーズマニュアル

The sixteen DIP-Switches and two berg jumpers control various modem
options or set default values for the MT2834 Command mode.  There is a
difference in how several of the switches operate depending on whether
you are in synchronous or asynchronous mode (DIP-Switch #12).

Most communications software packages have installation procedures of
their own, which call for certain modem DIP-Switch settings. If you are
using a package other than MultiExpress, follow the software's instructions.

The vast majority of installations are similar, with the MT2834 being used
to dial up a remote installation where the call is automatically answered.
The factory default DIP-Switch settings are based on this assumption. The
following is a brief description and summary of the MT2834's DIP-Switch
