PIONEERPOS G24-LC manual Hang-up Call, Idle

Chapter 3: AT Commands Reference

Note: When ATDL is issued after a dialed number with comma digit:

•ATDL; (Voice) dials the exact number that was last dialed, including the DTMF tones sent.

•ATDL (Data/Fax) dials the addressing information only (comma and tones are discarded).

•If ATDL is sent before any Dial command was issued (mainly after Power On, when the last number is an empty field), the G24-L will return NO CARRIER, as mentioned in the ITU V.25-ter standard.

Example

atdl	//Last called number is "035658278"
ATDL: "035658278"
OK	//DATA call
atdl;
ATDL: "035658278"
OK
OK	//VOICE call
atdl	//Last called number is "035658278,123,78;"
ATDL: "035658278"
CONNECT	//DATA call
atdl;	//Last called number is "035658278,123,78"
ATDL: "035658278p123p78"
OK
OK	//VOICE call
1 2 3	//Sent as DTMF tones
...	//Pause
7 8	//Sent as DTMF tones

H, Hang-up Call

This command hangs up a call. The G24-L terminates the call whether it is a data or voice call, and whether it is an incoming, originating, waiting, or connected call.

A NO CARRIER message is returned to the terminal before the regular OK approval.

Note: To terminate (hang-up) a MO data/fax call while call is placed: Any character sent from the terminal to the G24-L causes the Data/Fax call termination, and NO CARRIER is sent from the G24-L to the terminal.

To terminate a held Voice call or to terminate a call out of a MTPY call, refer to “+CHLD, Call Related Supplementary Services Command” on page 3-23.

The following table shows the call states of the H command.

Call State	Response/Action
IDLE	Error 3 ("operation not allowed")
Single Active	Call released
MTPY Active	Call released (all calls)
Incoming call (RING)	Call released
