Hi,

If you want to only simply contrtol the switches, then I don't think you even need a modem.

Modem are "as far as I understand" would be required to control by exchanging high speed data for more complex applications.

for your very purpose of controlling you can do that only by using DTMF ........

Happy controlling.

PS: I would still however, encourage your working on modems with mcu as sooner or later we would need that too :)
