RS-232C Error Message

[gripper]

I've wrote program that receives data from RS-485 board and displayes it to my program.

It works fine, but after running about 1 month, it displays error message like this;

"No port is open. Check COM port setting in Configure".

This message is from following statement;

RS232Error = ReturnRS232Err();

if (RS232Error)
