Usage

You can also supply a options object to the constructor to customize the behavior of the switcher.

The following example is for a Xantech XT-SW41-4K18G:

new HDMISwitch(
    '/dev/cu.usbserial-145420',
    {
        Baud: 57600,
        ZeroIndexed: false,
        CommandEnd: '\r',
        MaxInputs: 4,
        Commands: {
            PowerOn: 'OUTON',
            PowerOff: 'OUTOFF',
            OutputSelect: 'OUT FR %d',
        }
    }
);
