Niall, It would help to know the Control model, but Fanuc and Mitsubishi usually bring their RS232 communication out to a standard RS232 25 pin connector, Fanuc post a bulletin for serial communication on their website , You can try obtaining a 'null modem' cable which has all the lines connected between the two ends for hardware handshaking etc.
But sometimes all that is required is that the hardware handshake lines on the 25pin end are jumpered together i.e. 4-5 6-8-20 and just the pins 2, 3 & 7 are used.
If you want drip feed then you may need hardware handshake.
Siemens, I am not sure of, but if they have a 25 pin D connector, the chances are it is standard RS232.
If you need the pin out for either cable, I could post it.
One nice source of a DNC program is the 'Terminal' program supplied with win 3.1, it will run under Win95/98. It operates better than Hyperterminal.
