When I use a PenMount Serial WinCE driver with PM6000 RS-232 or PM9000 controller, why does the touch function sometimes fail after system start up?
Please adjust the controller switch to non-PNP device. Since all PenMount RS-232 controller devices are Non-PNP in Windows CE, normally the RTS signal of the RS-232 is not used. However, sometimes the operating system send a RTS signal to the PenMount controller resulting in controller cessation after Windows CE starts up.
