Online-Command Mode Commands

Online-Command mode allows the Online mode data stream to be interrupted so that AT commands are recognized and processed. An escape sequence, injected into the data stream, directs the modem to enter Online-Command mode from Online mode.

All AT commands recognized in Command mode are also recognized in Online-Command mode. The H command and the O command are of particular use in Online-Command mode.

When the Control port is active, the +++ escape sequence and the O command return their normal success status, even though the Control port’s operating mode has not changed from Command mode.

Change from Online to Online-Command Mode (+++)

 

Syntax

 

~+++~

 

Description

 

The escape sequence that directs the modem to change from

 

Online to Online-Command mode. Although this is not an AT

 

command, it is necessary to support Online-Command mode

 

and is, therefore, listed here for easy reference.

 

The ~ character indicates the “guard-time” both before and

 

after the escape sequence. This “guard-time” is necessary to

 

differentiate between the escape sequence +++ and any other

 

string of three + characters inside the Online data stream.

 

EIA/TIA/IS-707A defines the length of the “guard-time” as

 

“an appropriate time.” The modem defines the “guard-time”

 

to be 1 second.

Note

The “+++” string is transmitted through to the host side, even if the

escape sequence is recognized.

 

 

Valid Value(s)
