                        APPENDIX C.  ALPHABETICAL COMMAND SUMMARY
                                                                 
      
      Additional command summaries are on the
      bottom panel of the modem and in the
      Quick-Reference Card.
      
REQUIREMENTS

      1.Type commands in either upper or
         lower case, not a combination.
      2.All commands except A/ and +++ are
         preceded by the AT prefix and are
         executed with the Enter/Carriage
         Return key (<Enter>).
      3.Command length = 40 characters
         maximum.  The modem doesn't count the
         AT prefix, Carriage Return character,
         or spaces.  In a dial string, it
         counts but doesn't act on punctuation
         such as hyphens and parentheses.
      4.A missing numeric parameter is
         assumed to be zero, as in the command
         to hang up:  ATH <Enter> is the equiv
         alent of ATH0 <Enter>.
         
BASIC COMMAND SET

&     See the Extended Command Summary that
      follows this Basic Set.
A     Force Answer mode/Manual Answer.  The
      modem goes off hook in Answer mode when
      it detects a ring on the phone line, and
      sends an answer tone.  If it fails to
      detect a carrier signal from a calling
      modem within 60 seconds, it hangs up and
      Manual Answer mode is cancelled.
      Pressing any key after the modem goes
      off hook aborts the manual answer
      operation and hangs up the modem.
A/    Re-execute the last issued command.
      Used to redial.  A/ doesn't take the AT
      prefix or a Carriage Return.
Any key    Abort current connection attempt
      resulting from an issued D or A command.
AT    Attention:  lets the modem know commands
      are being issued to it.  Must precede
      all other commands except A/ and +++.

          required for modems answering
          overseas calls at 1200 and 2400
          bps.
      B1 Bell answer tone, United States and
          Canada.

      entering Online-Command mode and sending
      the OK result code.  If S14=1, the modem
      responds to the escape code by hanging
      up, returning to Command mode, and
      sending the NO CARRIER result code.
