Serial Port Complete: COM Ports, USB Virtual COM Ports, and Ports for Embedded Systems by Jan Axelson is a definitive guide for developers who need to bridge the gap between PCs and embedded hardware. Despite the rise of USB, serial communication remains essential for its simplicity, cost-effectiveness, and ability to handle long-distance links—up to 4,000 feet with RS-485. Why Serial Still Wins in Embedded Systems Implementing protocols to ensure data integrity over long
