Table 2-1.		Data Mode Command Summary (Continued)


Note		Command	Function	Default	Range	Reported by
Note		Command	Function	Default	Range	&Vn

		&D0	In Async mode, modem ignores DTR

			Modem switches from data mode to com-
		&D1	mand mode when an on-to-off transition of
			DTR occurs

			When DTR switches off, the modem goes on-
		&D2	hook and disables Auto-answer mode; when
			DTR switches on, auto-answer is enabled

		&D3	Turning off DTR re-initializes the modem and
		&D3	resets values except UART registers
			resets values except UART registers

		&F	Load factory defaults	none	–	no

*		&Gn	Guard tone option (1200 bps and 2400 bps	0	0–2	yes
*		&Gn	only)	0	0–2	yes
			only)

		&G0	Disables guard tone

		&G1	Enables 550-Hz guard tone

		&G2	Enables 1800-Hz guard tone

		&Kn	Select serial flow control	3	0, 3, 4	yes

		&K0	Disables flow control

		&K3	Bidirectional hardware flow control

		&K4	XON/XOFF software flow control

*		&Q0	ports only Async mode	0	0	yes
			ports only Async mode

*		&Sn	DSR (data set ready) option	0	0, 1	yes

		&S0	DSR is always active

		&S1	DSR active only during handshaking and
		&S1	when carrier is lost
			when carrier is lost

		&Tn	Self test commands	0	0, 1, 8	no

		&T0	Terminates test in progress

		&T1	Initiates local analog loopback

		&T8	Initiates local analog loopback with self-test

*		&Un	Disable Trellis coding	0	0, 1	yes

		&U0	Enables Trellis coding with QAM as fallback

		&U1	QAM modulation only

		&Vn	View active and stored profiles	0	0, 1	no

		&V0	View active profile and stored profile 0

		&V1	View active profile and stored profile 1
