USB to serial driver for FT232R in QNX 6.4.1


I am using a module which incorporates FT232RL IC from FTDI. The module is used to convert the serial data into USB and
pass it onto PC through the USB lines…

Now i need to work this project on my QNX 6.4.1 platform, the data transfer and all is working fine, but i need to know
how to access the port or GPIO or CBUS pins of the IC so that i can call some function and make the CBUS pins
controllable through software.

Can anyone please help me in this , it will be very needy …

Thank you
