3.6 SETUP PAGE 4—SERIAL CONSOLE
The ROM BIOS includes a unique set of features which allow full access to the system at any time over
standard RS232 serial ports. An embedded system may take advantage of these remote access capabilities
using the serial console functions in the following ways:
Serial console—Use Serial 1 or Serial 2 as a console, replacing the standard video monitor and keyboard.
Serial boot loader—Boot off Serial 1 or Serial 2 much like you would boot from a local hard disk or
from a network. (This is configured on Page 2 of SETUP.)
Serial programming—Automatically update system software, such as an SSD, through Serial 1 or Serial
2. This feature allows you to write new code into a Flash device installed in a byte-wide socket. It also
provides a means of upgrading the ROM BIOS itself.
For more information about these serial console functions, see “Serial Console Features,” under “Serial
Ports”, later in this chapter. For a thorough explanation of the serial console features, refer to Ampro
Application Note AAN-9403.
