6.3Console Redirection to a Serial Port
In many applications without a video card it may be necessary to obtain keyboard and monitor access to the CPU for configuration, file transfer, or other operations. Prometheus supports this operation by enabling keyboard input and character output onto a serial port (console redirection). A serial port on another PC can be connected to the serial port on Prometheus with a null modem cable, and a terminal emulation program (such as Hyperterminal) can be used to establish the connection. The terminal program must be capable of transmitting special characters including F2 (some programs or configurations trap special characters).
The default Prometheus BIOS setting enables console redirection onto COM2 during POST (power on
There are three possible configurations for console redirection:
♦POST only (default)
♦Always On
♦Disabled
To modify the console redirection settings, enter the BIOS, select the Advanced menu, and then select Console Redirection. In Com Port Address, select Disabled to disable the function, On- board COM A for COM1, or
If you select Disabled, you will not be able to enter BIOS again during
Before erasing CMOS RAM, write down any custom BIOS settings you have made!
If you erase the CMOS RAM, the next time the CPU powers up COM2 will return to the default settings of 115.2Kbaud, N, 8, 1 and operate only during POST.
If you selected COMA or COMB, then continue with the configuration:
For Console Type select PC ANSI. You can modify the baud rate and flow control here if desired.
At the bottom, for Continue C.R. after POST, select Off (default) to turn off after POST or select On to remain on always.
Exit the BIOS and save your settings.
