V.92 DIALUP 2-WIRE OR 4-WIRE LEASED-LINE DATA/FAX MODEM AT COMMANDS GUIDE
12
Command: &V n Display current configuration and statistics for last connection
Values: n = 0 or 1
Default: None
Description: &V0 Displays the current (active) configuration.
&V1 Displays statistics for the last connection. Not available in all
versions.
NOTE
See also the L5 command.
Command: &W n Store Current Configuration
Values: n = 0 or 1
Default: None
Description: &W0 Stores current modem settings in nonvolatile memory as
Profile 0. Profile 0 is loaded instead of the factory defaults at
power-on (if &Y0 is set) and by the ATZ command.
&W1 Stores current modem settings in nonvolatile memory as
Profile 1. Profile 1 is loaded instead of the factory defaults at
power-on (if &Y1 is set) and by the ATZ1 command.
NOTE
See also the Z, &F, and &Y commands.
Command: &X
n
Synchronous Clock Source
Values: n = 0, 1, or 2
Default: 0
Description: Selects the source of the transmit clock for synchronous mode. In
asynchronous mode, the transmit and receive clocks are turned off. In
synchronous mode, the clocks are turned on with a frequency of 1200
Hz or faster corresponding to the speed selected for modem operation.
NOTE
Synchronous Online (&M1) must be enabled before you can set the synchronous
clock.
&X0 Selects internal timing. The modem generates the transmit
clock signal and applies it to the TXCLK output at the serial
interface.
&X1 Selects external timing. The local DTE sources the transmit
clock signal on the XTCLK input of the serial interface. The
modem applies this clock to the TXCLK output at the serial
interface.
&X2 Selects slave receive timing. The modem derives the transmit
clock signal from the incoming carrier and applies it to the
TXCLK output at the serial interface.
