Online-Command Mode Commands

Integrator’s Reference Manual

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
	Note	escape sequence is recognized.
		escape sequence is recognized.
		Valid Value(s)
		N/A.
