This sounds really cool. I assume the TRRS connections mean RX audio, TX
audio, PTT, and GND/Common. Is there no provision for COR/Carrier detect as
one might get from the standard 6-pin mini-DIN data port? Or does this device
do CD in software with no hardware connection needed?
Am I correct in assuming that this device can run independently from a PC,
using the USB port exclusively for 5 VDC power input, after using a PC
connection to configure it?
By the way, Sabrent is now offering an FDTI-based serial<-->USB dongle. You
might look into carrying these instead of the problematic Prolific-based ones.
