Hello Evryone!
I use jSerial library to connect to some device on serial/usb port.
I've a class that manage the connection with the devices and I'd like to catch the "Port not found" exception if the specified port doesn't exist.
I've used this code in the class that manage the connections:
and in the main module I use the this code to connect and catch the exception:
But the execution in case of not found port ends on "exc.Throw" line on the connection class with the exception "jssc.SerialPortException: Port name - COM11; Method name - openPort(); Exception type - Port not found." without propagate the exception to the main module.
What I'm missing or doing wrong?
Thanks for the attention.
