6-2 PP 41x/03x

6.1.1 PC BIOS Serial Console

With some operating systems, or in some applications, it is preferable to use a serial terminal as an

operator console device for the board. In other cases, a standard VGA screen and PC keyboard

will be required.

The PP 41x/03x can be configured for operation with either a VGA screen or keyboard or with a

serial console. A board switch selects the console mode, as shown in Figure 6-1 below.

When configured in serial console mode, the PC BIOS firmware will re-direct its output to a serial

port, and similarly will take its input from this port, rather than using the VGA screen and PC

keyboard.

Figure 6-1 Console Switch

The serial line speed used for the Serial Console mode may be selected from the BIOS Setup

screen for Main configuration.
