1. Put the FLM file and the new modem firmware file (e.g., V1400DS.S37)
in an appropriate directory on the computers 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:
AT** or AT**0 Download speed is the last sensed speed (recommend-
ed command).
AT**1 Download speed is 38.4k bps.
AT**2 Download speed is 57.6k bps.
The Download Initiated message appears upon issuing the AT**n
command.
5. Perform an ASCII upload of the FLM file (e.g., AMDE.S37) from the host
computer to the modem RAM using an industry standard communica-
tions software or an equivalent process (ensure that all ASCII translation
or pacing is turned off). To abort the load at this point, wait for the
FLM download process to time-out, send a bad S37 record, or reset the
modem. If the load process times-out, the modem must be reset (ATZ)
before the FLM can be loaded again.
6. After the FLM has been loaded, perform an ASCII upload of the new
modem firmware hex file (e.g., RC288ACi.S37) from the host computer
to the modem RAM using an industry standard communications
software or an equivalent process. There will be a 3-second pause after
the first record of the RC288AXX.S37 file is sent, which is the FLASH
erase cycle. There is no turning back at this point. If the flash
download fails (because of a bad .S37 record for example) or the
upload is aborted, as long as the modem is not turned off or reset, it
will remain in the flash load cycle and the upload can be re-attempted
at step 5.
A Wrong Device message is displayed if an incorrect FLM is used. In
this case, restart at step 5 and upload the correct FLM file.
A Wrong Hex file or flow control message is displayed if an
incompatible hex file format is used (non-Motorola S3 format) or if the
DTE ignores flow control (the flash download uses both Xon/Xoff and
