//unplug the device

port.drain((err) => { 
    if(err){
         console.log(err)
    }
}

the callback just isn’t called.

@HipsterBrown sure, what I meant is something like this:

function callback(err) {
    if(error){
        console.log('write error: ' + error)
    }
    console.log('written')
}

var timeout = setTimeout(() => {
    callback('port write timed out')
}, 1500);

port.write(message, error => {
    clearTimeout(timeout)
    callback(error)
})

not nice at all though.
