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.replica watches replica watches replica watches
