A client for CMT's laptimer.

This application will receive a "millis" time from an arduino via a serial port, calculate the corresponding laptime, and then write it to a file.

The laptime client assumes that it will be reading bytes over a serial port. In particular, it expects that the bytes provided will be integers, delimited by a newline character ("\n").

If no newline character is passed over the serial port then the program will seem to hang forever, never writing anything to file or producing any output.
