serialEvent() stops being called after a few hours #57

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
We have an application that listens on a com port for data, but in certain 
scenarios, which we cannot yet reproduce, after a couple of hours the 
serialEvent() is simply no longer called when data is sent to the com port.
We have connected another third-party software AccessPort to the same device 
using a serial cable splitter, and it receives the data without problem.
This is not a problem however at any of our other installations, only this one.
We are using a RS232 to USB converter.

Using:
JSSC 2.6.0
Windows 8 Pro (64)

What are the scenarios that could cause this to happen? Do we need to send some 
kind of heart-beat to keep the com connection active? What is the best practice 
for long term com connections?

Thanks for any help!
