Instructions for MT100SEM firmware update 1.01c to 1.02b

It is recommended that the upgrade is performed on a developer board if possible.
If the upgrade is to be peformed in an embedded system, hardware (RTS/CTS) flow control must be implemented.
Setup terminal application to 115200bps 8 none and 1 CTS/RTS flow control. 
Make sure the terminal application is NOT configured to transmit linefeed characters with carriage returns.
The terminal program should have a binary mode file send option (TeraTerm is recommended).

With terminal program configured as above send an AT command and verify the MT100SEM responds.
Send command: AT+IFC=2,2
Send command: AT&W
send command: AT** (modem will respond with 'Download initiated...')
send file: 'uploader.a79' (use a binary transfer mode. In TeraTerm this is set with a checkbox in the fileselection dialog)
The modem will respond with '.. Download flash code ..'
send file: MTS_CONVERT_FILE.a79 (again use binary transfer mode)
When transfer is complete cycle power on the MT100SEM
send command: AT**
send file: AT91UP04_20DF00.s37 (use binary mode)
send file: HnQx102b.hex
