Nor have I. Obviously, "blind dialing", is dialing in the absence of dial tone. Recalling my modem days, some countries prohibited this activity. Others allowed it, but may also require you to recognize their dial tone when you were not in blind dial mode. Why would it be prohibited? A) Someone could already be talking on that line you've seized (hence, no tone); B) The exchange cannot place your call (recognize your DTMF) until it is ready to do so, ie has sent dial tone, you'd be tying up a line on a call that can't go through. In some countries, dial tone is not present for several seconds*, without "wait for dial tone", or a pause inserted in the string, most dial attempts would be unsuccessful. *(which I had proven in many countries to be outside their own spec's) Best regards, Stephen
