Modem Command Descriptions

A/ — Re-execute

Parameters none

Defaultnone

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 none

Defaultnone

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.

Result Codes

CONNECT XXXX	If a connection is established (XXXX = telco line
	speed, e.g. 2400)
NO CARRIER	If a connection cannot be established, the abort
	timer (register S7) expires, or if the command is
	aborted
