The C module has the same half-hearted attempt to do level shifting
that the R board uses. Most often, this will work with a USB->Serial
cable just fine. You can check the following information by referring
to the C module and R board schematics and working through the
connections.

Transmit data comes out of the module on pin 1, receive comes into the
module on pin 2. Ground is on pin 4.

You need to connect these to a female DB-9 connector. Transmit data
goes to pin 2 of the DB-9, receive data goes to pin 3. Ground goes to
pin 5.

Finally, make sure your USB COM port is in a range acceptable to the
IDE. I'm not on a Windows box at the moment so I can't check the
range. If necessary, use Device Manager on Windows to reassign the
COM port.
