It appears that all lines that start in a semicolon are comments
The rest of the lines need the whitespace stripped from beginning and end
and then it appears to be tab delimited. The first field is a sequence number
and irrelevant. The second field is a funky timestamp, then message id, etc as
shown in the file comments. The bytes seem to be space delimited and in hex
