Is there a way to temporarily close Port opened by another app ?

[webgourou]

Hi,

is there a way to close a serial comm port temporarily used by an other app in order to use it with jSerialComm ? Or even to force to retrieve data in the soft.

It seems that there is such implementations in .net development because the app using port could run simultaneously with an other app.

Right now I am not able to open port...

Thanks
