Is it possible to connect any USB RS232 directly to FrSky receiver and pass that to PC?
Yes & No
FrSky has his own inverted RS232 USB cable, this can be connected from TX module to PC.
Else you need an inverter.
Even if the Telemetry channel is 9600 bounds, FrSky state to don't use more then 2000 bounds.
I just made my first code for a Arduino Nano V3 (actually I could have even used a single chip ATtiny85 but I don't have it) ... that just invert the RS232 signal, so I can feed the bluetooth module from the FrSky TX module ... and it is working fine ... I can see telemetry data on my mobile phone now
In this way I could even implement some uplink commands ...
