CHAPTER 5: Command Mode
When this is done, the modem escapes to Command Mode, executes
the command (if any), and then remain in Command mode. For
example, to hang up the modem at the end of a call, enter +++ATH and
hit RETURN. There is no need to incorporate pauses before and after
the plus signs, as done in earlier modems.
BREAK AT<CR>
The Series II Modem provides an alternative Escape method, using a
Break signal as the Escape Code. The Break signal allows the start-stop
DTE (data terminal equipment) to signal the modem without loss of
character transparency. With this method, a BREAK signal is used
instead of the three plus signs. The BREAK is followed by the letters A
and T, up to 60 command characters, and RETURN. When this is done,
the modem executes that command, but remains in On-Line mode
unless the command was to hang up and/or reset the modem (an H or
Z), in which case the modem would be in the Command Mode after ex-
ecuting that command.
Escape Sequence Options - Entering Command Mode
While On-Line %E
As mentioned, the default escape sequence setting is for the modem to
respond to the +++ escape method. Optional settings are for the
modem to respond to the Break method, for the modem to respond to
either the +++ or the Break Methods, for the modem to ignore both
methods and not escape, for the modem to respond with no "OK" to
+++, and for the modem to respond with "OK" to +++. The %E com-
mand is used to select these options, as follows:
%E0 = Modem Won’t Escape
%E1 = +++ AT<CR> Method (default)
%E2 = Break Method
%E3 = Either +++ or Break Methods
%E4* = No "OK" Response to +++
%E5* = "OK" Response to +++
* The %E4 and %E5 commands enable or disable an "OK" response,
which is required by some software packages during an escape
sequence.
