Hi!
I'm a student too, and I made a VI very similar to yours. My VI used the
serial port to communicate with a modem, exchanging Hayes commands and
answer from the modem.
- Ma sei italiano anke tu! io non ho usato la VISA, ho usato solo le
funzioni relative alla porta seriale messe in due o tre frame, non ricordo
bene.. credo venga più complicato ma funziona! se vuoi vederlo scrivimi una
mail! -
