Flush buffer #39

Open bvwj opened 6 years ago

bvwj commented 6 years ago

It seems when I open a port and execute a read there can be old data in the buffer. I have to disconnect/reconnect the USB-UART to clear the old data.

I do not see any flush function. Is flushing the buffer possible?

If you import "io/ioutil" you can call ioutil.ReadAll on your serial port object. However, it does not appear to time out and I can't find a way to make this function return. I have both an InterCharacterTimeout of 2 set and a MinimumReadSize of 1.
