it requires that the phase be continuous. Since 2200 isn't an even
multiple of 1200 baud it wouldn't come out even anyway. In the
OpenTracker, a pointer to the current sine value is incremented each
step. The size of the increment depends on which tone is being sent
at the moment.</SPAN></FONT></DIV>
