AT Command Processing Modes

Data services AT command processing consists of three modes:

•Command mode — While in the Command mode, data service is inactive and the DCE processes AT commands received on the Rm interface.

•Online mode — Online mode is entered when a data connection is established and data service becomes active. While in the Online mode, the DCE does not recognize AT commands on the Rm interface, but does process in-band control data and software flow control data.

•Online-Command mode — During Online-Command mode, data service is in the active state, although data is not processed. The DCE processes all AT commands received on the Rm interface while in Online-Command mode.

Steps

TO ENTER ONLINE-COMMAND MODE FROM ONLINE MODE

 

 

■ Use an in-band control data escape sequence, “+++”

 

surrounded by guard time (see Change from Online to

 

Online-Command Mode (+++) on page 6-40).

 

or

 

Turn OFF the Rm interface DTR (circuit 108/2) signal

 

(see DTE Data Terminal Ready Behavior (&D) on page
