2. Three "+" characters are sent. The time interval that passes between two "+" characters should not exceed
1 second.
3. No data is sent to TTY for 2 seconds.
4. TTY switches to ESCAPE mode and sends OK response. The response format depends on the ATV and ATQ
commands. See AT-command set on page 49 for more information on these commands.
To switch from ESCAPE back to ONLINE mode, issue the ATO command. To drop the connection and return to
COMMAND mode, issue the "ATH" command.
In ESCAPE mode, you can read the S-registers, view the modem profile, and change port timeout and TTY
interface related values, but you cannot issue DIAL and ANSWER commands.
To change the ESCAPE character or to disable or enable the ESCAPE sequence, use the S2 S-register.
