Just use a 25 to 9 pin standard serialport adapter. I use a jdm programer that has a 9 pin connector that plugs straite in to a 9 pin serial port ( on a 1 to 1 9 pin exstention lead). At home my PC has a 25 pin serial port and i purchased a 9-25 pin adapter from Maplin.
Do not get confused with the type of adapter you would use for a serial port modem as these have a diferant pin assinment.
