Thanks for the quick response.
To clarify a little: -
a) I wanted to let Labview users know that accessing other than through the Labview hook in the TC08 DLL would be 'fun / trouble'
b) That attempting to access the TC08 using Labview's serial drivers thus bypassing the TC08 DLL is not straight forward. I can confirm that the RTS/DTR were in the correct state measued using a Fluke Oscilloscope. I can confirm that my code sent the correct bytes to the TC08 and arrived on the correct pin of the serial port at the TC08. (This is just to let you know its fun out here - not to get you to fix some end users bad coding).
1) Did you have an alternate technique for accessing the internal temperature reference using Labview.
2) Is there a chance that rev 5.08 TC08 DLL could be updated to allow labview to access more functionality from the TC08. i.e. The internal temperature reference ?
3) What time scale are we looking at for any update of the driver ?
