I am trying to use SIM300 GSM Modem with 16f877. When I connect it to PC, it works ONLY when the flow control is set to XON/XOFF in the com port setting. It works well with hyperterminal. When I connect it to uC, it just does not communicate.
On the other hand I have a wavecom Modem, which works with PC when the flow control is set to HARDWARE. When I connect this to uC, it works absolutely fine.
Can anybody guide me on this? In case the code and schematic had problems, the setup would not have worked with the wavecom modem.
