    UI Freeze while transmitting via RS232

    Hi all,
    I'm having a problem, my UI freeze while I transmit and receiving data thru RS232. The program works just that the UI freeze for a while. It return to normal after the Tx/Rx completed in RS232. I wonder why. I try many things like Update the UI thru invalidata and updatewindow method in the function that sends the data but it doesnt help at all. Pls help, tq.

    You should move your code for RS232 communications to the secondary thread(s)

    Ditto. You need to create a worker thread for the transmitting/receiving of the data.
