setTimeout and serialport interaction

[cleoo]

Hi,

I'm trying to use a timer to evaluate if the device i'm using is still responding, with a code like that:

[...]
serial.write(request);
dead_timer = setTimeout(() => { set device is dead }, 5000);

[...]
serial.on('data', response => {
clearTimeout(dead_timer);
[...]
})

But the code don't work anymore as expected. The timer freeze the data event during 5000ms, unless I "deref" the timer object. Can someone explain this behavior ?

Ps: I'm using Linux Arch, node 11.5.0, latest serial port.

Same issue, I'm going to close this for #1751. We'll either pull the release or release an update.
