Detecting port busy is not working as expected #4

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Open the port for device#1 ( USB device that has a virtual port ex: 
/dev/ttyACM0)
2. Open the port/dev/ttyACM0 again, and it succeeds where it should throw an 
exception, and this cause device#1 to stop functioning, and isCTS() starts to 
return "false".

What is the expected output? What do you see instead?
Throw an exception, instead the port is opened successfully

What version of the product are you using? On what operating system?
Version 0.9 , OS: Ubuntu 9.10

Please provide any additional information below.

I tested jSSC on Ubuntu 9.10 and I have no problems on this OS. Can you tell me 
version of libstdc++ library from your system ?

Me too, libstdc++.so.6.0.10 Hmm, it's interesting. Are you working under root 
user ? TIOCEXCL directive for exclusive access has no effect while working 
under root.

The issue because I'm working under root, if there is nothing you could do 
about it in the code, then I guess you can close it.

thanks, that was very helpful.
