The linear flash memory downloader in the modem firmware 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 (downloads) the data to the flash memory device. Note

that this downloader function must be provided in modem MCU firmware

initially installed in external flash memory, i.e., the downloader does not

support the programming of blank flash memory. Programming the flash

memory device is a two-step process:

A. When the AT** command is issued, the modem firmware boot loader

is invoked and you will first load a flash load module (FLM) into the

modem’s RAM. The FLM contains the programming algorithm for the

flash memory device being programmed and any messages that may

be sent during the load process.

B. Load the new modem firmware which the FLM will then program into

the flash memory device.

1. Put the FLM file and the new modem firmware file (e.g., V1400DS.S37)

in an appropriate directory on the computer’s hard disk.

2. Configure the communications application program for a DTE rate of

between 9600 bps and 57600 bps and RTS/CTS flow control. A load

at 57600 bps will take approximately 2 minutes; a load at 19200 bps

will take approximately 6 minutes.

3. Check the modem for response by typing AT.

4. Initiate the download process using the AT**n command, where:
