Multi-Tech Systems MT5634SMI V.92 manual Command $RPn Ring Priority vs. AT Command Priority, +Vdr?

			Chapter 1 – AT Commands, S-Registers and Result Codes
Command:	$RPn	Ring Priority vs. AT Command Priority
Values:		n = 0 or 1
Default:		1
Description:		$RP0 The AT command will have priority over the ring. S1 will be reset to 0
		if an AT command is received. This command is storable to memory.
		$RP1 The ring will have priority over the AT command. S1 will increment
		even if an AT command and ring are received together and the incoming
		call will be answered when S1 is equal to S0.
		Note: SocketModems do not detect ring cadence of TelTone telephone
		line simulators as a valid ring.
Command:	$SBn	Serial Port Baud Rate
Values:		n= speed in bits per second
Default:		57600
Description:		$SB300Sets serial port to 300 bps
		$SB1200 Sets serial port to 1200 bps
		$SB2400 Sets serial port to 2400 bps
		$SB4800 Sets serial port to 4800 bps
		$SB9600 Sets serial port to 9600 bps
		$SB19200 Sets serial port to 19200 bps
		$SB38400 Sets serial port to 38400 bps
		$SB57600 Sets serial port to 57600 bps
		$SB115200 Sets serial port to 115200 bps
		$SB230400 Sets serial port to 230400 bps
Command:	+VDR=x, y	Distinctive Ring Report
Values:		x = 0, 1 Distinctive Ring report control. See description.
		y = 0–255 Minimum ring interval in 100 ms units. See description.
Default:		0, 0
Description:		Enables reporting of ring cadence information to the DTE and specifies the
		minimum ring cadence that will be reported.
		The report format is one line per silence period and one line per ring period.
		The length of the silence period is in the form DROF=number in units of 100
		ms<CR><LF>, and the length of the ring is in the form DRON=number in
		units of 100 ms<CR> <LF>. The modem may produce a Ring event code
		after the DRON message if enabled by the y parameter. The y parameter
		must be set to a value equal to or smaller than the expected ring cadence in
		order to pass the report to the DTE.
		+VDR=0, N/A	Disables Distinctive Ring cadence reporting.
		+VDR=1, 0	Enables Distinctive Ring cadence reporting. Other call
			progress result codes (including RING) are reported as
			normal.
		+VDR=1, >0 Enables Distinctive Ring cadence reporting. The RING result
			code is reported after the falling edge of the ring pulse (i.e.,
			after the DRON report).
		+VDR=?	Displays the allowed values.
		+VDR?	Displays the current value.
