Hi, Robert. Thanks for your help.

I'm a bit confused with this part of your answer: "Serial ports come in two
"flavors": computer and non-computer. Because Pocket PCs commonly connect to
computers, their serial ports are set up as NON-computer.".

Is this correct? Aren't the Pocket PCs setted to connect to computers?

Thanks again,

Fabrício.
