[time-nuts] Thunderbolt PPS Modification

[Ed Palmer]

I was thinking of modifying my Tbolt to put the 1 PPS on one of the 
unused RS-232 leads.  It just seems like it would be really convenient 
to have that signal available to import into a computer.

It looks like it's not going to be quite as simple as I'd hoped.  So 
before I reinvent the wheel, has anyone done this mod and could you 
offer any suggestions or warnings?

Thanks,
Ed
