## Usage

```python
from mcp_rs232 import list_ports, open_port, close_port, read_port, write_port

# List available ports
ports = list_ports()
print(ports)

# Open a port
open_port("COM1", baud_rate=9600)

# Write data (hex encoded)
write_port("COM1", "48656c6c6f")  # "Hello"

# Read data (returns hex encoded)
data = read_port("COM1")

# Close the port
close_port("COM1")
```

## CLI
