Using serial ports as the foundation for wireless communication links. Despite the rise of USB, serial communication remains
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 Despite the rise of USB
While standard peripherals have largely migrated to USB, serial ports (COM ports) are often the better choice for specific engineering needs:
Jan Axelson provides practical, code-heavy examples for both PC software and microcontroller firmware:
Serial ports can use significantly longer cables than USB allows—ideal for harsh industrial environments.
