Niall, The pin out you state is standard RS232, the jumpered pins are to fool out the hardware handshake and Xon/Xoff in the settings indicate it is set for software handshake. You did not mention what software you are using for transfer. If you have quite a few machines, it is usefull to have a program like Terminal I mentioned earlier which enables you to set up a protocol for each machine if they require different characteristics.
Dropped characters are usually a sign of improper handshake. You may need to confirm the CNC machine parameters to ensure they are set up for Xon/Xoff software HS.
But most of these machines will report errors if any occur on data transfer.
If you still have problems, try a null modem cable and see if that helps on the machines you are having a problem with. it cannot hurt.
