This is the switch that selects between the data acq temp measuring
RS232 modules and the GPS RS232. Can any of you electronic types
see any problems with this?

look at maxim for rs 232 chips which have a tristate on the outputs i
believe. maxim-ic.com.

Thanks.
Found some but not in stock. They are sending me samples from
the Philippines. What you see on the schematic is the parts I have
in stock. Another chip or two is not much trouble for me to 
wire up.
