4.3 Dual Port FT232 UART Interface Mode Description

The FT2232H can be configured in similar UART modes as the FTDI FT232 devices. The following

examples illustrate how to configure the FT2232H with an RS232, RS422 or RS485 interface. The FT2232

can be configured as a mixture of these interfaces.
