MultiModemII User Guide

Command:	&Qn	Sync/Async Mode
Values:		n = 0–3, 5, 6
Default:		5
Description:		This command is an extension of the &M command, and is used
		to control which connection modes are permitted. It is used in
		conjunction with S36 and S48. (See also the \N command.)
	&Q0	Selects direct asynchronous operation. See &M0.
	&Q1	Selects synchronous connect mode with asynchronous offline
		command mode. See &M1. (Serial interface operation only.)
	&Q2	Selects synchronous connect mode with asynchronous offline
		command mode and enables DTR dialing of directory 3. See
		&M2. (Serial interface operation only.)
	&Q3	Selects synchronous connect mode with asynchronous offline
		command mode and enables DTR to act as a talk/data switch.
		See &M3. (Serial interface operation only.)
	&Q5	The modem will try to negotiate an error-corrected link. The
		modem can be configured using S36 to determine whether a
		failure will result in the modem disconnecting or falling back
		to a non-error-correction connection. See also \N3.
	&Q6	Selects asynchronous operation with speed buffering and no
		error correction. Same as \N0.
Command:	&Rn	Clear to Send (CTS) Control
Values:		n = 0 or 1
Default:		1
Description:	&R0	Let the CTS state follow the RTS state when online..
	&R1	Force CTS high (ON).
Command:	&Sn	Data Set Ready (DSR) Control
Values:		n = 0 or 1
Default:		0
Description:	&S0	Force DSR high (on) at all times.
	&S1	Let DSR go high only during a connection.
Command:	&Tn	V.54 Test Commands
Values:		n = 0, 1, 3, 4, 5, 6, 7, or 8
Default:		None
Description:		The modem can perform selected test and diagnostic functions. A
		test can be run only when the modem is in asynchronous op-
		eration in non-error-correction mode (normal or direct mode).
		For tests 3, 6, and 7, a connection between the two modems
		must first be established. To terminate a test in progress, the
		escape sequence (+++) must be entered first, except for param-
		eters 7 and 8. If S18 is non-zero, a test terminates automatically
		after the time specified by S18 and displays the OK message.
	&T0	Abort. Stop any test in progress.
	&T1	Start local analog loopback, V.54 Loop 3. If a connection exists
		when this command is issued, the modem hangs up. A CON-
		NECT message is displayed at the start of the test.
	&T3	Start local digital loopback, V.54 Loop 2. If no connection exists,
		ERROR is returned.
