Command

Default

 

Description

 

 

 

 

 

Identify Product Revision: This command causes the DCE to report the modem chipset revision level.

 

 

This command is identical to AT+FREV? and AT+FMR. The response message depends on the

+GMR

none

firmware version.

AT+GMR

 

 

 

 

 

 

536EP Release 4.28 - Dec 10 2001

 

 

OK

 

 

 

 

 

 

Request Product Serial Number Identification: This command causes the DCE to transmit a message

 

 

to the DTE indicating the product serial number identification.

 

 

Syntax:

 

+GSN

none

AT+GSN

 

+GSN: PCI\VEN_8086&DEV_1040&SUBSYS_00000000&REV_00

 

 

 

 

OK

 

 

 

The modem responds with the hardware Id key from the registry that contains the VendorID, SubVendor

 

 

Id, Subsystem VendorId, Device ID, and hardware revision.

 

 

 

 

 

DTE-DCE Local Flow Control: Controls the flow control between local DTE and DCE when V.42 error

 

 

control or normal mode (buffering mode or speed matching) is being used. In addition to acting locally

 

 

the flow control characters can be passed on to remote DCE to act upon. It accepts two numeric

 

 

subparameters:

 

 

<DCE_by_DTE> specifies the method to be used by the DTE to control the flow of received data from

 

 

the DCE; and

 

 

 

<DTE_by_DCE> specifies the method to be used by the DCE to control the flow of transmitted data from

 

 

the DTE.

 

 

 

<DCE_by_DTE>

DC1/DC3 software flow control; do not pass DC1/DC3 characters to the remote DCE

 

 

2

RTS/CTS—hardware flow control

 

 

3

DC1/DC3 software flow control with DC1/DC3 characters being passed to the remote DCE

 

 

 

in addition to being acted upon for local flow control

 

 

<DTE_by_DCE>

DCI/DC3 software flow control

 

 

2

RTS/CTS hardware flow control

 

 

 

 

 

DTE to DCE Local Rate Reporting: Controls whether the “+ILRR:” result code is transmitted from the

 

 

DCE to the DTE once a connection has been made. If enabled the result code displayed shall represent

 

 

the current negotiated DTE-DCE rate, and is issued after any Modulation (+MR:), Error Control (+ER:) or

 

 

Data Compression (+DR:) reports and before the final result code “CONNECT”. +ILRR accepts one

+ILRR=m

0

numeric parameter decimal value and the format is as follows:

0

Disables reporting of local port rate (no +ILRR intermediate result code transmitted)

 

 

 

 

1

Enables reporting of local port rate (+ILRR intermediate result code transmitted)

 

 

Example response message when +ILRR = 1,

 

 

+ILRR: 19200

 

 

 

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