Proprietary AT Command Set

COMMUNICATIONS MODE
Type:	Configuration
Format:	AT [cmds] &Q n [cmds]
Description:	Selects communications mode options
Command	Mode
&Q0	Asynchronous mode, serial port speed follows connect speed.
&Q1	Asynchronous off-line command mode and synchronous connect mode.
&Q2	Asynchronous off-line command mode - modem autodials first number in directory, then synchronous connect mode.
&Q3	Asynchronous off-line command mode on low DTR, synchronous connect mode on high DTR.
&Q5	Error correction mode
&Q6	Buffered asynchronous mode

DIAL
Type:	Immediate
Format:	AT [cmds] D<#> [cmds]
Description:	Dials telephone number according to any modifiers included in the string
Note:	Any combination of modifiers can be used to produce the desired dial functions in sequence.
Command	Function
DL	Re-dial last number
DP	Pulse dialing enabled
DS=n	Dial stored telephone number n
DT	Tone dialing enabled/Pulse dialing disabled
DW	Dialing resumed following dial tone detection
D,	Dialing paused for amount of time specified in S8 register
D!	Flash function initiated. Modem commanded to go off-hook for specified time before returning on-hook.
D@	Wait for Quiet Answer function enabled. Modem waits until a "quiet answer," a ring-back signal followed by silence up to the time specified in S7, is received prior to executing the rest of the dial string.
D&	Calling card "Bong" detection enabled. Waits for credit card dialing tone for amount of time specified by the S7 command.
D;	Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command.
D^	Enables/disbables calling tone
