INTERFACE TO SOFTWARE USING USB DEVICE NAME
For Non-OPOS application, the application software has to control pole display
operation accordingly through the USB device port. To send data to the pole display,
the application software has to open and access the device port with device name
\\.\lcld9\. Please see <Sample.c> source code listing for example of using the device
name.
The pole display is controlled by command codes and data from the PC. Refer to the
Command Set on the left or User Manual for details. Note that as DOS does not
support USB, it may not be possible to test the USB pole display with DOS prompt
commands. It can only be tested under application software.
