connectivity problems, determining the proper start and end of transmission bytes, and diagnosing device
problems.
The format is as follows:
Pkt(n): ddd:hh:mm:ss.mmm Rx/Tx:
Where:
ddd – days since last system restart
hh – hours since last system restart
mm – minutes since last system restart
ss – seconds since last system restart
mmm – milliseconds since last system restart
