So far all I have done is strip the RS232 level shifter and support
components off the USB-serial adapter, leaving the FTDI chip behind.  I
need to cut the trace to the VCCIO pad and link it to 3V3OUT, then link
TxD and RxD together and off to a 4-way plug for the VX2r.  It's easy to
do, but it takes time.

I have also made a copy of the VX7 module and called it VX2, and it shows
up in the UI, but I can't do any more until I have a serial interface to
talk to.

I also installed VX2 commander under WINE, but I don't know if I'll use
it.  It runs, but of course I still need a serial device.

Thanks everyone for your interest.  I am writing this all down so that
someone can speak up if I am about to do something stupid.

73,
