Notes:
* Relevant Options

* Scott: The TOCALL field can't be changed - it's fixed at APOTxx.
* Scott: HBAUD is ignored for now. When I've had more time to test it, it'll support other FSK baud rates, but it won't do 300 or 1200 baud AFSK.

On Linux:
Plug in
'dmesg' command to see the USB port associated. Mine was /tty/devASM0 ??

Plug in
Find Unknown USB Device
Update software with .INF file from Argent. Full instructions at:
I had to update twice. The first time it wouldn't start.

Wishlist and tweaks:
* Adjustable faster HBAUD speeds
* Change the TOCALL field
* Remove the software carrier detect switch. It probably doesn't apply.
