Windows Com Ports

[MikeM]

Hi,
I'm trying to use Rebol Serial Port with my Bluetooth link.  The serial port works fine on "normal" COM ports, and on a USB serial adaptor.  It will not take COM10 as a valid COM port - which is what my Bluetooth software assigns as the COM port for a serial connection.

Does REBOL have a limit on COM ports?

Thanks
Mike M
