Parallel Buffer
Purpose:
To configure the size of the parallel input buffer.

Purpose:
To control the pull-up resistors on the parallel port signals. This menu item is useful for personal
computers that have open collector outputs on the parallel port signals.

Parallel Mode 2
Purpose:
To determine whether the parallel port data is sampled on the leading or trailing edge of strobe.
Values:
