Data Mode AT COMMANDS
+GMR none
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
firmware version.
AT+GMR
536EP Release 4.28 - Dec 10 2001
OK
+GSN none
Request Product Serial Number Identification: This command causes the DCE to transmit a message
to the DTE indicating the product serial number identification.
Syntax:
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>
0 none
1 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>
0 None
1 DCI/DC3 software flow control
2 RTS/CTS hardware flow control
+ILRR=m 0
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
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
