Implements support for touch devices.


For a touch device to be effectively used, the POINTDD.SYS device driver and appropriate mouse device-driver support must be loaded. In addition, these statements must be included in the CONFIG.SYS file in the following order:

  • A device-dependent statement that gives the name of the file containing the information for the touch device you use.
  • A device-independent statement that identifies the touch device to TOUCH.SYS
  • If during installation, OS/2 detects a touch device installed on your system, the Install program automatically loads the required device-driver support necessary to enable the touch device. The touch device shares the auxiliary device (mouse) port on the system with the mouse by allowing the mouse to connect to the touch device, which is then connected to the system.
  • The Install program automatically adds the following statements to the CONFIG.SYS file:
  • "x" is 1 or 2 depending on the bus architecture of your system. TOUCO21D.BIN is the touch-device microcode binary file and TOUCH.INI is a text file containing default parameter settings.
  • The RUN=CALIBRAT.EXE statement is to activate the Calibration program. This program performs the dual actions of downloading calibration-constant data to the touch device each time the system is started, and enabling recalibration of the touch device at initial setup, and when the device is moved to a new location.
  • To recalibrate the touch device, enter the following at an OS/2 command prompt:
x: (where "x" is your OS/2 boot drive.)
