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
that is selected for modem operation.
&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
