Multi-Tech Systems MT5600SMI-XL92 Command Plug and Play Vendor ID and Product Number, Procedure

		Chapter 5 – AT Commands, S-Registers, and Result Codes
Command	%8	Plug and Play Vendor ID and Product Number
Description:		Sets and stores Vendor ID and product number for serial Plug and Play
		and for ISA Plug and Play which use the Conexant 11596 Plug and Play
		device. Applicable to Desktop configuration only.
Default:		None
Example:		%8<3 ASCII characters><4 hex numbers><same 3 ASCII
		characters><same 4 hex numbers><cr>
Result Codes:		OK <3 ASCII characters><4 hex numbers><same 3 ASCII
		characters><same 4 hex numbers>
		Otherwise ERROR
Command	**	Load Flash Memory
Description:		The linear flash memory uploader allows flash memory connected to the
		modem external memory bus to be upgraded with revised modem
		firmware. This process transfers (uploads) the upgraded modem firmware
		(data) from the host computer to the modem which transfers the data to the
		flash memory device. The linear flash memory downloader allows the flash
		memory connected to the modem external memory bus to read and saved.
		This process transfers (downloads) the current modem firmware (data) to
		the host computer. Uploading new firmware to the flash memory or
		downloading existing firmware from the flash memory device is a two-step
		process.
		1. When the AT** command is issued, the modem firmware boot loader is
		invoked and the user will first load a flash load module (FLM) into the
		modem's RAM. If the user wishes to upload new firmware to the
		modem, he should load the uploader FLM. If the user wishes to
		download existing firmware from the modem, he should load the
		downloader FLM. In either case, the data transfer is done via an ASCII
		transfer. The FLM contains the programming algorithm for the flash
		memory device being programmed and any messages that may be sent
		during the load process.
		2. If the user wishes to upload new firmware to the modem, then he will
		then load the new modem firmware, which the uploader FLM will then
		program into the flash memory device. This transfer is done via
		XMODEM transfer. If the user wishes to download existing firmware
		from the modem, then he will set up the host PC for XMODEM receive
		and the downloader FLM will begin to send the existing firmware from
		the flash memory to the host PC.

Procedure

1.Install in the modem a flash memory programmed with the modem firmware or a blank flash memory.

2.Put the uploader FLM and downloader FLM files and the new modem firmware file (e.g., XmUL003.s37, XmDL003.s37, and 206s4712.S37) in an appropriate directory on the computer's hard disk.

3.Configure the communications application program for a DTE rate of between 9600 bps and 115200 bps and RTS/CTS flow control.

4.Check the modem for response by typing AT.

5.Initiate the download process using the AT** command. The "Download flash code…" message appears upon issuing the AT** command.

6.Perform an ASCII transfer of the FLM file (e.g., XmUL003.s37 for uploading new firmware to the modem or XmDL003.s37 for downloading existing firmware from the modem) from the host computer to the modem RAM using an industry standard communications software or an equivalent process (ensure that all ASCII translation or pacing is turned off).
