Why is COM port 1 not available on the AppSrvCE unit?
Article Number: 502 | Rating: Unrated | Last Updated: Mon, Jul 14, 2014 at 8:30 AM

The latest AppSrvCE platform, v1.23, includes ELO USB and serial touch screen drivers.  COM1 is allocated by the touch screen serial driver, whether or not a serial touch screen is actually present.  As a result COM1 is not available to any other application.

To disable the ELO touch screen it is necessary to edit the registry key HKLM/Hardware/Devicemap/Touch/ComPort and change the name to an unused or nonexistent port (e.g., COM7). This will prevent COM1 from being used for the touch screen.
