im simulating a terminal and to exit the running test i have to send Ctrl+C. im using VISA Write/Read. everything works just fine except the Ctrl+C command.
i tried String: 03, 3, /03 accordingly to ascii table. but nothing seems to work.
So there is a problem in your VI, but you don't attach that VI and still expect us to find the problem?
Have you also tried to send a byte containing the value "3"?
Have you tried to set your string to Hex display mode and then type the "03" value?
(never mind this reply, GerdW already said it but I read too fast)
My guess is that you didn't send 3, but 51. Set the string control to display hex. But as GerdW says, without seeing your VI, we can only guess.

Well, your VI was the problem as your code was not created as you should have created the code…
But my magic glass ball was right!
Setting string constant's or control's mode to "\ Codes Display" and entering \03 (and not /03) would also have given you that result. It definitely was a problem in your VI so attaching that VI or at least showing your diagram or even better yet a snippet of your VI, would have made it easily recognizable without forcing Gerd to invoke his magic glass ball in guessing what the problem could be.
