+++ Escape sequence
The escape sequence allows the modem to exit data mode and enter on-line command mode. While in on-line
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 which is set by the Escape Guard Time (S12), must be used before and 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.
