01. Refactored SerialInputOutputManager (#615) 
Used separate threads for reading and writing, enhancing concurrency and performance.

Note: before was possible to start `SerialInputOutputManager` with `Executors.newSingleThreadExecutor().submit(ioManager)`. Now you have to use `ioManager.start()`

kai-morich 5f94a47b63 read w/o timeout now only throws exception on connection lost 
partly revert f4166f34, as there might be unkown reasons for empty response
 2021-04-20 22:53:53 +02:00
kai-morich 128d1a00b1 new SerialInputOutputManager.start() method 
Previously recommended start action `Executors.newSingleThreadExecutor().submit(ioManager)` did not shutdown the Executor, which caused a thread leak. It's still possible to use old style start, as SerialInputOutputManager continues to implement Runnable interface.

kai-morich 4ffcc8d0fb simplify write timeout handling 2021-02-13 21:07:21 +01:00
kai-morich f60414f8ec improve write timeout handling 
Return type of write() method changed to void. The return value was redundant before, as it always was the request length or an exception was thrown.

If timeout is reached, write() now throws a SerialTimeoutException with ex.bytesTransferred filled with known transferred bytes.

Added CommonUsbSerialPort.getReadEndpoint() and .getWriteEndpoint() to assist in setting the optimal write buffer size with port.setWriteBufferSize(port.getWriteEndpoint().getMaxPacketSize()).

By default the write buffer size is > MaxPacketSize and the Linux kernel splits writes in chunks. When the timeout occurs, it's unknown how many chunks have already been transferred and the exception typically stores 0. With optimal write buffer size, this value is known and stored in SerialTimeoutException, but due to more kernel round trips write() might take slightly longer().

kai-morich 7423fd9d79 new getControlLines() and getSupportedControLines() methods 
getControlLines() requires less USB calls than calling getRTS() + ... + getRI() individually.
getSupportedControlLines() tells you, which control lines are supported by a driver. Previously you had to check the driver implementation.
