The setting for these switches are vital to the proper operation of the modem.
Even if the NVRAM is set correctly, the modem will still look to the state of the
switches upon power-up and can override any NVRAM settings if not set
correctly.
Switch 1 (DOWN): Data Terminal Ready Override. Forces modem to ignore
DTR.
Switch 2 (DOWN): Numeric Result Codes. Codes that are issued for certain
status indicators numeric or text format such as 0, 3, or 4.
Switch 3 (UP): Suppress Result Codes. Modem will not issue commands to
verify command has been received.
Switch 4 (DOWN): No echo, offline commands. Modem will copy each
