Win32 COMM API
Application
FTD2XX.DLL FTSER2K.SYS
FTDI provides two alternative software
interfaces for USB controllers.
COM Port Application
One interface provides a Virtual COM Port
(VCP) which appears to the system as a
legacy COM port. Legacy applications
should work with VCP drivers with minimal
modification.

D2XX API
The second interface, D2XX, is provided via
a proprietary DLL (FTD2XX.DLL). The D2XX
interface provides special functions to
optimize performance and improve
flexibility.
