I'm trying to send out a message through the serial port. I'm not having any problems sending the data, I'm having problems getting it to stop when the message has been sent once. Ideally, I want to be able to click my mouse on a picture, based on the position of the mouse a particular message will be sent out the serial port and the program will wait for another mouse click. I have the mouse part going, now I just need a hand with getting it to send a message, one time, when the mouse is clicked. Thanks for the help!
