I wonder where will you connect the usb side of the usb to ttl converter to a microcontroller ! Ofcourse you can check it with a PC.
First confirm whether your sim900 module has a max232 built in or not. If not you have to add one externally. Learn this project, the circuit diagram will be useful for you.
