AT Command Set
Issue 2 November 1996
A-3
Command: +++
Function: Escape sequence.
Type: immediate
Arguments: none
S-Register: S2 and S12
Example: +++
Comments: The purpose of the +++ command is to provide a way to
switch the 8400B Plus Data Module from on-line or data
mode to command mode without disconnecting a data
call that is in progress. As long as the call is not
disconnected, you can return to the data mode with the
O command.
This is one of the two commands that does not require
the AT prefix (A/ is the other one), and it is never
followed by pressing . The value in S12
determines how long your keyboard should remain idle
before entering the escape sequence, as well as the
maximum allowable time between entering each
character of the sequence. The character used in the
escape sequence is determined by the value in S2
(default is ASCII 43, the plus sign).

page 3-10, the 0 command on page A-14, S2 on page
C-9, and S12 on page C-19.
