Hello,

I am using a Cube Orange+ running PX4 and I am having an issue getting telem2 to receive the UART data that I am sending from a Radar that I have attached. I checked the connections for RX and TX, made sure that the Driver for the Radar was looking at the correct Serial Port. The issue that I am running into is that the Radar is sending ASCII characters over UART but when I look at the data that is being received over the serial connection. The characters are not the expected ascii characters. I am not sure if you all can help me but I figure that it is worth a try.

```auto
nsh> INFO [omni_radar] Printing Info On Radar: 40
