Python - Aborting a read with pySerial |

I'm using pySerial to read from a serial port.
One thread reads from the port, with no timeout. Another thread handles output and other tasks. This works fine until I want to shut down the program. I can't reliably break the program out of the read when it's waiting. On Windows, closing the serial port will abort the read, but that seems to have no effect on Linux. I know, I could put a timeout on the read and handle all those null returns. Is there a better way? John Nagle John Nagle |
