[amsat-bb] SatPC32 Radio frequency control

[alriccio1]

I am having a problem getting SatPC32 satellite frequency control to work.  I have a IC-9100 radio and an Apple Pro laptop
connected via a USB cable.  Com ports 1 & 2 and SiliconLabs CP210x USB to UART bridge are listed in my PC ports list.
Inputing these ports  into the SatPC32 program does not do anything.  The frequency display on the IC-9100 does not change
even after a reboot .  Can someone take me through the proper steps?
