#4823 - control through telephone lines |
Hi friends,
I would like to design a control card which would dial some numbers when i press * or # buttons.. ý ve heard that there are some special button frequency oriented IC... for this kind of a function, do i need a mController such as 80c51, or flash prom... Are there some similar solutions? Thanks for your interests, EB |
