1.1 Driver Support

The FT4232H requires USB drivers (listed below) , available free from http://www.ftdichip.com, which

are used to make the FT4232H appear as a virtual COM port (VCP). This allows the user to communicate

with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB

driver, the D2XX driver, can also be used with application software to directly access the FT4232H

through a DLL.
