Chapter 7: AT Commands and Registers

	&T1 makes the modem display the characters on your screen
	exactly as you type them. The modem must be in normal or direct
	mode and set to 1200 bps or higher.
	&T3 allows a remote modem that does not support the ITU-T
	V.54 standard to perform a Remote Digital Loopback test with
	your modem. The modem must connect in normal or direct mode
	and be set to 1200 bps or higher.
	&T4 allows the modem to respond to a remote caller’s request to
	enter Remote Digital Loopback mode.
	&T5 prevents the modem from responding to a Remote Digital
	Loopback request.
	&T6 instructs the remote modem to initiate a Remote Digital
	Loopback. It is available only when the modem is connected in
	normal or direct mode and set to 1200 bps or higher.
	&T7 instructs the remote modem to enter a Remote Digital
	Loopback with Self-Test. Upon completion of the test, the modem
	reports errors to the local device. This command is available only
	when the modem connects in normal or direct mode and is set to
	1200 bps or higher.
	&T8 makes the modem send itself the ITU-T V.54 test pattern
	and verify these characters. Upon completion of the test, the
	modem reports errors to the local device. This command is
	available only when the modem is in normal or direct mode and
	set to 1200 bps or higher.
\Tn	Inactivity Timer
	Where n is an integer from 0 and 90 in minutes (Default is 0).
	Specifies the number of minutes the modem waits for data before
	automatically hanging up. \T0 (default) disables the inactivity
	timer. The inactivity timer is only available during normal and
	reliable link connections; the modem ignores it in direct mode.
%Un	Clear Serial-Port Speed
%U0	Allows the current serial-port speed change from any speed.
%U1	Always keeps the current serial-port speed. To change serial-port
	speed, you must enter %U1 each time you change it.
%U2	Allows the current serial-port speed change from any speed.
