So it just braodcasts the data? I would try something like adding a serial poll to make sure the bits are there. Also note the initialization of the shift register.

We've given up on this particular temperature probe. Its very unreliable. Instead we are gonna use a Fluke GPIB multimeter and use some analog circuitry/labview to make a .01 degree accurate thermometer. Thanks for all the help jack.

I havent looked at the problem in much detail but would it be possible to get a GPIB driver for the piece of equipment that you use. They would have pre-built VIs which would have error handling and it may work.
It would just stop you from sweating around looking for a problem in your code...
