[GreenKeys] USB to RS-232

[Ron Boltz]

I do have two laptops with the RS-232 port and both of those are kept only
for that reason.  One runs XP the other win-7.  In their early work life, I
used them for machine interfaces as many older PLC's and other industrial
controllers used RS-232.  I'm looking to the future when batteries die or
other failures of these PC's.  I have replaced the hard drives in both of
these already and no telling how long parts will be available.
