I think you are on a wild goose chase.

You can get very accurate timing from a serial port without PPS when the text 
doesn't have fractions of a second.  All the hardware has to do is send the 
packet at a fixed time relative to the second tick.

GPS is the obvious example.  Well, mostly of how to do it wrong.  But you can 
get good timing from a few of them.
