Data Mode AT COMMANDS

Table 18. Data Mode Command Descriptions (Continued)

Command	Default		Description
		Selective Repeat: Controls the use of selective repeat (SREJ) option in V.42.
+ESR	1	0	Do not use SREJ
		1	Use SREJ if available in remote DCE; continue without it if not
		2	Use SREJ if available in remote DCE; disconnect if SREJ is not available
		Call Termination Buffer Management: Controls the handling of data remaining in the DCE buffers upon
		call termination. It accepts three numeric parameters:
		Syntax:
		+ETBM = <pending TD>, <pending RD>, <timer>
		<pending TD> controls how previously transmitted data remaining in the DCE buffers should be handled
		when the local DTE requests disconnection of the call.
		0	Discard all buffered data immediately and disconnect
		1	Attempt until all data is delivered and acknowledged (ignoring timer); if remote DCE
			disconnects discard remaining data
+ETBM	1, 1, 20	2	Attempt until all data is delivered and acknowledged; if timer expires or remote DCE
			disconnects, discard remaining data
		<pending RD> controls how previously received data remaining in the DCE buffers should be handled
		when the remote DCE disconnects the call.
		0	Discard all buffered data immediately and disconnect
		1	Attempt until all data is delivered (ignoring timer); if local DTE requests disconnect discard
			remaining data
		2	Attempt until all data is delivered; if timer expires or local DTE requests disconnect discard
			remaining data
		<timer> sets a maximum time limit that the DCE will attempt to deliver the buffered data before
		disconnecting and discarding the remaining
		0–30	Delivery timer value in seconds
		Request Complete Capabilities List: This extended-format command causes the DCE to transmit a list
		of additional capabilities commands.
+GCAP	none		AT+GCAP
			+GCAP: +FCLASS,+MS,+ES,+DS
			OK
		Identify Country of Installation: This extended command is used to indicate and select the country of
		installation for the DCE. The DTE may use this value to determine country-specific functions. To
		determine what countries the DCE supports, issue the AT+GCI=? command. Refer to the ITU-T T.35
+GCI=m	see ‘m’	recommendation for the details on what country code is used for each country.
		Default: country of installation
		m = country code, e.g., United States
			AT+GCI=B5
		Identify Modem Manufacturer: This command causes the DCE to send a message to the DTE
		indicating the DCE manufacturer. This command is identical to AT+FMFR? and AT+FMI.
+GMI	none		AT+GMI
			Intel Corporation
			OK
		Identify Product Model: This command causes the DCE to report the modem chipset name. This
		command is identical to AT+FMDL? and AT+FMM commands.
+GMM	none		AT+GMM
			Intel 536EP V.92 Modem
			OK
