Western Telematic SRM-100 - Manual (Page 13)

4.2.1. Default Modem Baud Rate (Sw1, Sw2)
SetUp Switches one and two select the default baud rate for the SRM’s internal modem and the
serial Modem Port. The Modem Baud Rate can also be selected via the Modem Parameters
Menu (/M). Note that if the unit is reset to default parameters, the Modem Baud Rate will
return to the default setting selected by SetUp Switches one and two.
Note: Automatic baud rate sensing is disabled. This allows the SRM to function
with devices that do not send an AT command string.

4.2.2. Default Flow Control Format (Sw3)
SetUp Switch three selects the default flow control (handshaking) format for the serial Modem
Port. The flow control format for the serial Modem Port can also be selected via the Modem
Parameters Menu. The flow control format for the internal modem itself is set using AT
commands as described in Section 9. Note that if the unit is reset to default parameters, the
flow control format will return to the default setting selected by SetUp Switch three.
