&X Modem Timing
This command is only valid for 2-wire V.22bis and V.22 full-duplex
operation. It determines the timing source for the modem
transmitter.
&X0 Internal timing (supplied by the modem). Use in
simple 2-wire point-to-point applications, whether
PSTN or leased line. Default.
&X1
External timing (supplied to modem on pin 24). Use
where the modem link is an extension of a network
which requires timing synchronisation throughout.
Applicable in 2-wire half-duplex systems.
&X2 Slave timing (derived from receive timing). Use where
a link requires one timing source for both transmission
directions, and the timing is determined by the remote
device.
The following diagrams illustrate the use of &X command:

%X Remote Up-Load
This command is used to request a copy of the remote modem's
active configuration. This will momentarily interrupt data
transmission.
