My labview program communicates with a serial device using visa. It
works on the development system. When I build it to an exe and move it
to the target system, there are no errors, but communication is timing
out.

I know the target system hardware is good because I can communicate
using hyperterminal. Also note that after running exe app, then
running hyperterminal, if I send <enter> I get a bunch of replies to
strings sent from exe app.
