PIC18F USART Go-back-N ARQ demonstration

http://www.waitingforfriday.com/index.php/PIC18F_USART_implementation_with_Go-back-N_ARQ

This video shows a demonstration of 2 PIC18F2550s communicating over a USART serial link. The communication stack supports flow-control, error-correction using CRC16 and a Go-Back-N ARQ sliding window mechanism. In the video you can see the Tx and Rx lines interrupted and the DTE and DCE being reset, the LED status indication shows the stack recovery mechanism in action. For more details please see the project page on my website.
