Intel Confidential

Data Mode AT COMMANDS

+ESR

1

Selective Repeat: Controls the use of selective repeat (SREJ) option in V.42.

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

+ETBM

1, 1, 20

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

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

+GCAP

none

Request Complete Capabilities List: This extended-format command causes the DCE to transmit a list
of additional capabilities commands.

AT+GCAP

+GCAP: +FCLASS,+MS,+ES,+DS

OK

+GCI=m

see ‘m’

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
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

+GMI

none

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.

AT+GMI

Intel Corporation

OK

+GMM

none

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.

AT+GMM

Intel 536EP V.92 Modem

OK
