One of the foundational components of device communication, especially when integrating various modules (like Wi-Fi, LoRa, LTE, BLE, and more), is the utilization of Serial communication. The simplicity and ubiquity of Serial communication make it a prevalent choice in many applications.

In endeavors involving the W5100S-EVB-Pico, or even the Raspberry Pi Pico, a common requirement is the ability to manage multiple Serial ports. Why? It allows for a streamlined process in juggling multiple communication tasks, especially when attempting to interface with numerous devices or modules simultaneously. Recognizing this need, I've crafted a "Serial to Serial2" example tailored for the Arduino IDE environment.

Here's how it functions: When data is received on the W5100S-EVB-Pico's USB Port (labeled as Serial), it is instantly relayed to Serial2 (associated with GPIO 8 and GPIO 9). This ensures seamless data transmission between these two ports. Conversely, the system is adept at receiving data from Serial2 and instantly relaying it to the primary Serial port, demonstrating bidirectional communication.

This example serves as a pivotal tool for developers aiming to craft sophisticated applications with the W5100S-EVB-Pico, simplifying the intricacies of multi-serial communication. Whether you're a seasoned developer or just getting started, this example provides a sturdy framework to enhance your projects.
