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
