Code: Arduino sends double linefeed signals at the end of the line when seen via cat
When reading from /dev/ttyACM0 via cat with -A switch enabled I can see empty lines in between PPS string time stamps.
This might be because cat (bat too) does this somehow, or that we have an extra Serial.println() statement. This might be a problem when reading from serial. So far doesn't seem like it, but it's worth noticing
