Howto make a newline with minicom after a timeout

Question

I'm running minicom in hex mode:

minicom -D /dev/ttyACM0 -H

Now I'm getting all the hex value I want to read. Is it possible to make a newline after receiving nothing for a specific time?

Now I'm receiving something like this:

fc 1c 55 4c 35 31

Between the last to hex values is a delay of ~100ms. So I would like to break the line after 50ms. So the result looks like:

fc 1c 55 4c 35
31

Probably a different serial terminal can handle this?

I'm on Ubuntu Mate 1804.
