C++ Builder and USB<->RS232

[vital060]

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.

I buy ft232r breakout boards rather than the convertor cables.... then I only need the usb A to B leads...

Writing to a CDC device is exactly the same as writing to a RS232 COM port.... Once the CDC firmware is installed it will enumerate the USB port that the chips connected to as COMx... You just use that port in Builder.

I have used this library in the past, it works quite well (it will ding dang do!)

It has 2 MDIO channels. One is CFP compatible running at 1.2V with 4MHz MDC frequency.
SUB-20 has integration modules for LabView. Low price, good support, reliability. What else?
We use SUB-20 as I2C master as well and also via LabView module.
