3.1Menu
The menu at the top of the application offers a series of quick options for how the COM port is to behave.
1.File → Exit - Terminates the application
2.Settings → Port - Selects from COM1 to COM4. Default is COM4.
The serial port's actual port number defaults to what we have specified on
“USB_Drivers_Install_Readme.pdf”. However, any port between COM 1 and COM 4 are equally usable.
3.Connect: Opens the serial port. When this menu item is pressed, its caption changes to “Disconnect”.
4.Disconnect: Closes the serial port. When this menu item is pressed, its caption changes to “Connect”.
After opening the application, the order of events should be:
1.Go to Settings → Port and choose the COM port where the USB virtual COM port device has been configured to work. If the COM port is 4, then this step can be skipped as application defaults to COM4.
2.Press Connect. If the port is available, the menu changes the “Connect“ caption to “Disconnect“. Press Disconnect to disable the serial communications.
