implement write timeout #17

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
A write operation is blocking endless when a virtual port is removed during a 
write operation. It unblocks only if SerialPort.closePort() will be called by 
an other thread.

Some thougs about implementation variants:

1. void write(byte[] data,long writeTimeoutMs)
   Writes the data and wait at most writeTimeoutMs milliseconds to resume, otherwise an    IOException or a Subtype will be thrown eg. IOTimeoutException

2. Future<Integer> write(byte[] data)
   Writes the data non blocking and returns a Future that can be consumed later. Its like the "overlapped" API for Windows. The Future returns the written bytes or throws an ExecutionException containig the cause SerialPortException

3. provide an additional method setWriteTimeout(long writeTimeoutMs) to set the 
Timeout that should be used for the next write operation.

Hi,

I have an application which sends a reset command to an external device (via 
bluetooth). The next write is typically not possible since its not avaliable 
anymore. This causes my UI-Thread to hang infinitely. Is their anything I could 
help to get this fixed? its very urgent to me..

THX

hi,

your suggestion to close it from another thread is not working for me, so it 
would be really good to get this fixed. it crashed my whole application on 
windows.

THX!
