Compatibility with other WINTAB Drivers

Only one WINTAB driver can control a serial port at a time. If you wish to use this driver in conjunction with any other Windows pointing device, plug your digitizer into another serial port. You will be able to use either driver by plugging your digitizer into the appropriate serial port. Some drivers attempt to probe both serial ports. If your current driver does this, it must be completely disabled or removed from your system.
