Re: [amsat-bb] Sat Programs to USB Interfacing

[Jim Jerzycke <kq6ea@xxxxxxxxxxx>]

I've only used Keyspan adapters, so YMMV, but the
included software handles assigning "virtual" comm
ports to the USB device. Rather than having separate
"dongles" for each USB-to-Serial adapter, I purchased
a Keyspan USA-49WLC adapter that has 4 serial ports in
it. Just keeps the desk neater, and I now have a
couple of "spare" comm ports if I need them.

It works perfectly under Windoze and Linux.
