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

 

 

 

 

NOTE: An asterisk (*) denotes the factory-default setting.
