RS485 Serial Bus

Exposes RS485 bus connectivity for reading and writing serial data with configurable connection parameters.

Provides tools for interacting with RS485 serial bus devices, including listing available serial ports, establishing connections with configurable parameters (baudrate, parity, stopbits, bytesize, timeout), and reading/writing data in hex format. Supports monitoring connection state and statistics. Useful for industrial automation, sensor networks, and hardware interfacing scenarios.
