 Switches 1, 2 & 3.  Selects bits per character for asynchronous operation,
or transmit (Tx) and receive (Rx) clock (C) for synchronous operation.
Factory set to 10 bits Asynchronous.

 Switches 1 2 3               1=on 0=off

          1 0 0        Asynchronous 8 bits
          1 1 0        Asynchronous 9 bits
          0 0 0        Asynchronous 10 bits     (Default)
          0 1 0        Asynchronous 11 bits
          1 0 1        Synchronous external TxC
          0 0 1        Synchronous internal TxC
          1 1 1        Synchronous TxC = RxC

 Switch 4 - Response disable.  If the hayes responses are not desired when
the modem is turned on, hten switch 4 should be set ON.  This switch has the
same effect as ATQ1.  Default = OFF.

 Switch 5 - Echo disable.  If it is not desired to echo the transmitted data
back to the terminal equipment while the modem is off-line, then switch 5
should be set ON.  This switch has the same effect as ATE0.  Default = OFF.

 Switch 6 - DTR.  Switch 6 must be ON if the terminal equipment does not
supply a DTR signal to the modem (via pin 20).  Default = OFF.

 Switch 7 - RTS.  Switch 7 must be set ON if the termial equipment does not
supply an RTS signal to the modem (via pin 4).  Default = OFF.

 Switch 8 - DSR.  For terminals that require DSR to be ON before operating,
switch 8 should be ON.  This enables hayes commands to be sent to the modem
in the offline state when DSR whould normally be OFF.  Default = ON.
