You can get Flash Magic to generate serial numbers by writing a Flash Magic Just In Time module.

This is a DOS/Windows executable that can be called on the command line and generates the desired hex file to program containing whatever you want. Flash Magic calls your program just before programming the device and automatically programs into the device whatever your module generated. This way your serial numbers can have any format you want.

To increment the numbers your module will need to write the last generated serial number to a file then each time it is run, read the file, increment and write back to the file.

Your program could also generate reports on serial numbers generated, tell the user at programming time what serial number was generated (so the operator can create a sticker for the hardware for example), etc., etc. Your program could even display a dialog window asking for a serial number to be entered.

Alternatively we can write this for you.
