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
Hi thanks for your reply.
When i send ATDT then number followed by return stroke(using pic), The modem doesn't respond. Therefore hyper-terminal must be setting or sending more data. To make a connection in hyperterminal i have to set baud rate to 9600 and hardware to none. So do i need more AT commands??
Please help
