Serial I/O
Serial Ports
The Osprey provides two serial ports. Both ports can be operated in RS-232, RS-422, or RS-485
mode. IRQ lines are chosen in the BIOS Setup utility. The UARTs are 16550-based serial ports
and are implemented in the FPGA.
Figure 20 shows the location and pin orientation of the serial I/O connector.
