Hello Roger4sun, Thank you for contacting National Instruments.
I'm not sure I understand your question. Are you looking for an interface that will call LabVIEW code? I searched on google and found a number of sites that offered emulators for sale. The following link leads to a site that offers 30 day trials of a VT 100 terminal. http://www.zephyrcorp.com/Downloads/terminal-emulator-download.htm Let me know if you have more questions. Sean C.
