Chapter 7: AT Commands and Registers
7-38 CSMIM-T1 Hardware Installation Guide
Save telephone numbers independently with the \Pn and &Zn=
commands. The *W command saves the serial-port speed and
parity and the modem-port speed in effect when you enter *W.
See also the &W, &Y, and Z commands. Refer to the section
entitled “Storing Multiple User Profiles” for details on multiple
user profiles.
The &W command setting stores default settings for the restricted
S-registers. If &W is issued after issuing *W, the default settings
for the restricted S-registers are stored. If you change the setting
of one of the restricted S-registers and want to save it, use the *W
command instead of the &W command.

Extended Result Codes
X0 Modem ignores dial tone and busy signals. Displays CONNECT
when it establishes a connection. Smartmodem 300 compatible.
X1 Modem ignores dial tone and busy signals. Sends a connect result
code including bps rate when it establishes a connection.
X2 Modem ignores busy signals. Displays NO DIALTONE if it does
not detect one within 5 seconds of dialing. Sends a connect result
code reflecting bps rate when it establishes a connection.
X3 Modem ignores dial tone. Displays BUSY if it detects a busy
signal. Sends a connect result code reflecting bps rate when it
establishes a connection.
X4 Displays NO DIALTONE if it does not detect one within 5
seconds of dialing. Displays BUSY if it detects a busy signal.
Sends a connect result code reflecting bps rate when it establishes
a connection.
Determines whether the modem responds to dial tone and busy
signals, and what kind of CONNECT result codes are displayed.
Result codes are further controlled by the Vn command. Result
codes indicate MNP reliable mode only when either \V1, \V2,
\V3, \V4, \V5 or -M1 is set. When the modem ignores dial tone,
it waits for the register S6 time delay to expire and then dials
regardless of whether a dial tone is present.
NOTE The &W and *W commands share the same stored
configuration area. Issue one of these commands to override
the other stored settings.
