If you don’t want to bother with writing your sourceapp and sinkapp in C++ programs, you can use Python and PySerial.

For quick and easy C++-style access to serial ports, use boost.asio as described in this tutorial.So, I had three programs: a sourceapp, a mainapp, and a sinkapp. I wanted to send/receive data to/from the application using the same programs, independent of whether the main app was running on Linux or the target. I had a target application, which I first wanted to test on Linux, and then wanted to run on an embedded system. The posting sums up a lot of what I used, but below is more detail. Here are some notes on what I found useful.įirst off, the last page I found after hours of Googling was the page I needed to find in the beginning, by someone who went through similar headaches, and has an aptly titled blog: “Retrospectively Obvious”. It was one of those frustrating situations, where it is a conceptually simple problem, which you know will be easy once you solve it, but where there are morasses of snippets of information to wade through on Google until you get to the particular solution you need. I wanted to be able to emulate and test the serial port communication before putting the application on the embedded device. I have just spent 10x longer than I would have expected getting serial-port communication working in C++ and Linux for an embedded system I am working on.
