Hardware flowcontrol can stuck the execution without any timeout #54

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
1 - Try to set the hardware flowcontrol and connect a software flowcontrol 
device or simply disconnect the serial cable.
2 - Open the port and write something.
3 - The thread lock and it became not interruptable (maybe the driver is 
waiting the CTS signal).

I tried to set up a timeout with a ThreadMonitor (see 
org.apache.commons.io.ThreadMonitor ) but the thread with the writing job is 
not interruptable.

How to avoid this deadlock? I know the flowcontrol must be set correctly, 
however if an user miss the setup he can stuck the application.
