So am I right in thinking there is no simple way to only call a read byte function when a byte is present in the buffer to be read?

I looked at the SerialPort documentation for C#, and I don't see a method of determining whether there is data to read, or not.

On the other hand, the derivation path for SerialPort makes it just another stream reader, and stream readers know to stop when the stream is empty. There might be an eof() function somewhere in it's derivation path that you could use to see if you are at the end of the stream.

If you use a thread to read the port, it doesn't matter that the thread blocks waiting for data.
