The settings 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 (UP): Verbal Result Codes. Codes that are issued for certain status
indicators in a text format such as OK, CONNECT, RING, NO CARRIER, etc.
Switch 3 (DOWN): Display Result Codes. Modem will issue commands to
verify certain operations such as connection speed and acknowledgments of
command.
