C++ Builder and USB<->RS232

[nasarat]

I am trying to make an application with C++Builder which communicates with a PIC16F877A which has a RS232 interface. Unfortunately my computer only has USB ports so I have bought a USB to RS232 converter cable.
Well I am a complete beginner to C++ Builder so really at this point I don't even know it will be possible to do this... Any help and advice would be really appreciated.

The driver for the USB device should give you the API needed to talk to the serial device transparently? I mean, with the device installed, just talk in C++ as if you did have an actual rs232 port. Make your first code initialize a COM port, 1 through 4, until you get a positive response, when successful, push some data and look for it on the port or grab some data from the port.
