Example Workflow

1. List available ports:

   serial_list_ports()
   

2. Open a connection:

   serial_open(port="COM3", baud_rate=115200)
   

3. Write data:

   serial_write(connection_id="conn_1", data="Hello, device!")
   

4. Read response:

   serial_read(connection_id="conn_1", timeout=2.0)
