SECURE RACK MODEM
Command
Function/Options
N
n
Enable/Disable Automode.
N0
Disable automode detection (equivalent to
setting the +MS<automode> subparameter to 0).
A subsequent handshake will be conducted as
specified by register S37, or if S37=0, according
to the most recently sensed DTE speed.
*N1
Enable automode detection (equivalent to
sMS<automode> subparameters to 1). A
subsequent handshake will be conducted as
specified by register S37, or if S37=0, starting at
28,800 bps V.34.
NOTES
The Nn and S37=
x
commands override the +MS command settings.
When the N0 or N1 command is issued, the +MS subparameters are
updated accordingly. For example, “N1S37=10” updates the +MS
command subparameters to reflect “+MS=10,1,300,12000”; while
“N0S37=10” updates the +MS command subparameters to
“+MS=10,0,300,12000”.
We recommend that you use the +MS commands instead of the Nn and
S37=
x
commands.
Nn and S37=
x
commands are supported for compatibility with existing
communication software.
O
n
Return to On-Line Mode.
O0
Switches modem from Command mode to on-
line mode after dropping to Command mode
using the escape sequence (
+++
).
O1
Switches from Command mode to on-line mode
and initiates an equalizer retrain sequence
before returning to on-line mode.
P
Set pulse dial as default. Forces pulse dialing until the next T dial
modifier or T command is received.
Q
n
Enable/disable result codes.
Q0
Enable result codes.
*Q1
Disable result codes (quiet mode).
