Thread interrupt not ending blocking call on input stream read

Question

I\'m using RXTX to read data from a serial port. The reading is done within a thread spawned in the following manner:

CommPortIdentifier portIdentifier = Co         


        

Answer 1

The RXTX SerialInputStream (what is returned by the serial.getInputStream() call) supports a timeout scheme that ended up solving all my problems. Adding the following before creating the new SerialReader object causes the reads to no longer block indefinitely:

serial.enableReceiveTimeout(1000);

Within the SerialReader object, I had to change a few things around to read directly from the InputStream instead of creating the ReadableByteChannel, but now, I can stop and restart the reader without issue.
