I used a cheap copy of a Nokia USB data cable, modelled on a CA-42. Most 
computers don't have RS232 serial connections any more.

Mine has a Prolific PL2303 chip in it, and by providing ground, 3v, and then 
connecting to your chosen USART Rx and Tx pins (this is chip-dependant), and 
setting your chip's BOOT pins correctly, you should be able to use this program.

Not all adaptors are wired up the same, and many use different colours for the 
wires, so you'll have to use the Nokia-side plug to test which wires have which 
function.

You can't use a modern one of course- all modern Nokias are natively USB.
