Modem Command Descriptions

A/ — Re-execute
Parameters
Default
Re-executes the most recent AT command string. The principle
application of this command is to place another call (e.g., Dial command)
that failed, to connect due to a busy line, no answer, or a wrong number.
This command must appear alone on a command line and must be
terminated by the "/" character. (An [ENTER] should not be entered to
terminate the command.)
A — Answer
Parameters
Default
This must be the last command entered into the command line. The
modem proceeds with the connect sequence in answer mode. The
modem will enter the connected state after exchanging carrier with the
remote modem. If no carrier is detected within a wait period specified in
register S7 (default = 30 seconds), the modem will disconnect. Any
further characters entered during the connect sequence will abort the
command.
