Stuart J. Birrell
A bidirectional serial-to-parallel converter was created to allow collection of serial data through the parallel port on a portable laptop computer. The converter consisted of both hardware conversion circuitry and control software. The converter supported both input and output at a variety of transmission formats and adjustable transmission rates. The control software made use of the various I/O registers of the parallel port to collect data and control the hardware circuitry.
