Hello,
I am trying to make an interface where you push a pushbutton on Advanced HMI and it will send an ASCII string (or other data) via one of the serial ports on the computer. For example, this application will have several keys (pushbuttons) such as the "BasicButton" from the "AdvancedHMIControls Components" or the "Button" from the "All Windows Forms". When you press that button I simply want to send a short string of data over one of the serial ports (or USB port that have a USB to DB9 converter) to a device that can be controlled serially. Any ideas on what the best approach is for this?
