I've encountered an issue when using the eclipse/mraa library's UART functionality in a C++ environment. The problem is that the first received message always starts with the hex value 0x13, corresponding to the ASCII control character 'Ctrl+S', why is this?

This behavior is not observed when using 'minicom' on my Rock Pi 4-se (https://wiki.radxa.com/Rockpi4/dev/serial-console).

I have followed and built the example code provided in the eclipse/mraa repository for C++, specifically the 'uart.cpp' example (https://github.com/eclipse/mraa/tree/master/examples/c%2B%2B).

Thank you.
