"Controller not Detected"

This message indicates a problem with the serial port connections, the controller or the controller power.

Signal Function DB9 Pin # Condition
DSR Indicates power to controller 6 Open or grounded

If comdump indicates data when the screen is touched, the touchscreen can probably be made to work by disabling hardware handshaking. Add -p- to the end of the ELODEV command line in autoexec.bat. Reboot the system afterwards.

Run comdump to determine which line is at fault, or to determine if there may be a touchscreen or controller problem.
