R = 10Kohm, Diode 1N4148 or similar.
Both uart tx and rx channels are used so it's not possible to use the spare pin for rx of something else.
Configure the serial port like this to get both serial rx and ibus telemetry on the same port:
```
serial 1 4160 115200 57600 115200 115200
```
It is still possible to run the serial rx and ibus telemetry on two uarts like before, an example:
```
serial 1 64 115200 57600 0 115200
serial 2 4096 115200 57600 115200 115200
```
