Dial-up PPP for an Embedded System

Real-Time and Embedded Systems Software Development

This project involved the following work for an Intel 386ex based product -

Writing interrupt driven serial port drivers capable of running at rates of up to 57600 Baud.
Integrating those drivers with a PPP library provided with the RTOS used by the product.
Designing how the dial-up PPP capability would be used and would be integrated into the product (that already used TCP/IP over Ethernet).
Writing the software to configure and control the conditions that cause the product to dial-up.

The software was written in C and C++, with a small amount of assembler for the interrupt service routines.
