of silence before the expiration of the call abort timer (S7), the modem will terminate the call attempt with a NO ANSWER message. If busy detection is enabled, the modem may terminate the call with the BUSY result code. If answer tone arrives during execution of this parameter, the modem handshakes.

&Wait for credit card dialing tone before continuing with the dial string. If the tone is not detected within the time specified by S7 (US models) or S6 (W-class models), the modem will abort the rest of the

sequence, return on-hook, and generate an error message.

,Dial pause: the modem will pause for a time specified by S8 before dialing the digits following ",".

;Return to command state. Added to the end of a dial string, this causes the modem to return to the command state after it processes the portion of the dial string preceding the ";". This allows the user to issue additional AT commands while remaining off-hook. The additional AT commands may be placed in the original command line following the ";" and/or may be entered on subsequent command

lines. The modem will enter call progress only after an additional dial command is issued without the ";" terminator. Use "H" to abort the dial in progress, and go back on-hook.

Command: T	Set Tone Dial Default
Description:	Forces DTMF dialing until the next P dial modifier or P command is
	received. The modem will set an S-Parameter bit to indicate that all
	subsequent dialing should be conducted in tone mode. The DP command
	will override this command. Clears S14 bit 5.
	This command may not be permitted in some countries. (See P.)
Result Code:	OK

Command: P	Set Pulse Dial Default
Description:	Forces pulse dialing until the next T dial modifier or T command is
	received. Sets S14 bit 5.
	As soon as a dial command is executed which explicitly specifies the
	dialing mode for that particular call (e.g., ATDT...), this command is
	overridden so that all future dialing will be tone dialed. (See T command.)
	This command may not be permitted in some countries.
Result Code:	OK
