1. Do I need any RS232 Converter in between Modem & Microcontroller?
2. What should be the connection diagram for Microcontroller to MODEM?
3. What is the pin Assignment for the output data pin of the said MODEM?
I am totally confused.Please help me if you have any Idea. Any help will be appriciated.
