Hi am trying to find out the required AT command set for a microcontroller to connect through rs232 to a modem and call a number. i can do so with hyperterminal with ATDT then number. is this sufficient for the pic to send this.
With AT set do i need to ECHO (E1)? Set Baud rate? Set Asyncronous(&Mn)
Any HELP please
"Your modem doesn't know - or care - what hardware and software you use to communicate with it."
Absolutely!
