The Heidenhain ND 281 B will output it's display ( from linear encoder) to my pc using Windows Hyper Terminal when I send Cntrl B. I cannot input Cntrl B into the send string on my LabVIEW example VI's. For my application I need LabVIEW to send and receive this between 100 and 1000 times per second, and use the data returned as a plot axis vs. time; and as a plot axis vs. an analog input signal (strain gauge force cell). Duplicate digital readout, also. Additionally, I need the point in time where the strain signal and serial signal occur not to be distorted.
