Flow Control, Voice Mode Result Codes | Technics MT5634SMI-92

			Chapter 6 – Voice Commands
Command:	+VPR=<rate>		Select DTE/DCE Interface Rate (Turn Off Autobaud)
Values:	0, 1, 2, 3, 4, 5, 6, 7, 8
Result Codes:	OK if the modem accepts the command; ERROR if the <rate> value is out of range.
Description:	The +VPR= command causes the modem to select between various fixed modem-to-PC interface
	rates and autobauding. The selected fixed interface rate stays in effect until the modem selects
	another interface rate or autobauding, or until the modem returns to autobauding on the expiration
	of the Inactivity Timer. The newly selected rate takes effect after the modem returns the OK result
	code.
	+VPR=0	select autobauding
	+VPR=1	select 2400 bps
	+VPR=2	select 4800 bps
	+VPR=3	select 7200 bps
	+VPR=4	select 9600 bps
	+VPR=5	select 12000 bps
	+VPR=6	select 14400 bps
	+VPR=7	select 16800 bps
	+VPR=8	select 19200 bps
	If the modem claims support for autobauding (+VPR=0), it means that the modem can accept AT
	commands at 2400 bps at all times while in Voice command mode and with +VPR=0.

Flow Control

XON/XOFF flow control is used by the SocketModem to match the PC-to-modem data rate to the line-signaling rate, as well as to the requirements of analog conversion of the voice signals and voice data.

In-band, uni-directional XON/XOFF flow control is mandatory. RTS/CTS (V.24 circuits 106 and 133) flow control is optional per the IS-101 standard.

Voice Mode Result Codes

In Voice mode, the modem can detect and report DTMF, detect call progress tone and cadence events, evaluate voice quality, and can monitor telco-related activities. Events can be reported as a single character (Simple or "Terse" reporting), a full-text message (Message or "Verbose" reporting), or as a repeating pattern (Pattern reporting).

7	Data Calling (e.g., 1300 Hz)
8	Local Phone On/Off Hook
9	Presumed Hang Up (SILENCE) Time-out
10	Presumed End of Message (QUIET) Time-out
11	SIT Tone (CO Standard Information Tones, sent to pay phones)
12	Bong Tone (Calling Card Tone)
13	Loop Current Interruption
14	Loop Current Polarity Reversal
15*	Call Waiting Beep/Interrupt*
16*	Distinctive Call Waiting*
17*	TDD Detected (e.g., 1400/1800 Hz)*
18	Ring Back/Remote Ring
19	BUSY
20	DIALTONE
21	Reorder/Fast Busy
22	V.21 Channel 2 7E Flags
