+++Escape sequence

The escape sequence allows the modem to exit data mode and enter online command mode. While in online command mode, you may communicate directly to your modem using AT commands. Once you are finished, you may return to data mode using the ATO command.

A pause, the length of which is set by the Escape Guard Time (S12), must be used after an escape sequence is issued. This pause prevents the modem from interpreting the escape sequence as data.

The value of the escape sequence character may be changed using Register S2.

$	Display AT Command List
	Displays a basic AT command list as well as online Help.
A/	Repeat Last Command
	Causes the modem immediately to repeat the previous command such as redialing a
	telephone number. The previously executed command remains in the command buffer
	until AT is entered or power is turned off. Both actions clear the buffer and make the A/
	command invalid since there is no command to repeat. It is not necessary to enter either a
	<cr> or AT.
A>	Repeat Last Command
	Causes the modem to continuously repeat the previous command such as redialing a
	telephone number. It is not necessary to enter either a <cr> or AT.
