// Minimal example: send and receive RS485 bytes over TCP via an Ethernet-to-RS485
// adapter (e.g. Waveshare). The adapter is transparent, bytes written to the TCP
// socket go out on the RS485 bus, and bytes received on RS485 arrive via TCP.
//
// Build:  g++-14 -std=c++23 -o tcp_example tcp_example.cpp
// Usage:  ./tcp_example 192.168.1.200 4196
