Description: ESCAPE SEQUENCE
This command is used to change the modem from data mode to command
mode. This command is not a Hayes-compatible command as the guard
time interval is not required. It is a public domain method (TIES) and is
only enabled with define VG_TIES_ESC_SEQUENCE.
If the modem receives the characters +++AT followed by a carriage return
(<cr>) within a 0.5 second time span, the modem interrupts the data flow
on the AT command interface, switches to command mode and interprets
all characters received before the next command line termination
character as commands.
This command can only be issued in data mode.
