Yes, well kind of. The only Free2move unit they have is the packaged
serial port device (at $142). They don't carry the bare module.

According to the Expansys website:

"No external drivers are needed to use the plug. A user-friendly Windows
application is included that can be used to configure the plug to suit your
requirements.
The software you have developed for your serial ports can remain unchanged
when using the paired serial cable plugs. Windows software for configuring
the Serial Port Plug is delivered for free."

So according to this, while you don't need the s/w stack, you may need to do
some setup/configuration (for which they provide the PC-side software). Did
you have to develop some PIC code to do this config? If so, where did you
get the techical info?

Thanks again.
