I have a serial device `/dev/ttyACM0`, that I would like to access it from the host and inside the docker container and this serial device is connected in a loop back mode (meaning i send a data, it will receive the same data)

I pass the serial device into the container as follow:

```auto
docker run -v /dev/ttyACM0:/dev/ttyACM0 node

```

I have an application inside the docker container that sends a message every 1 second,

In my host, I have the same application that receives the message send from the application inside container, and resend the message.

I found that, there is a some problem when I did this, sometimes I will get data corruption,

- i) is it possible to share the serial device and open it at same time from host and container?
- ii) what are the disadvantage of doing this?
- iii) how can i solve the data corruption problems?
