EDIRECTION
The VL-EPMs-21 can be operated without using the on-board video output by redirecting the
console to a serial communications port. CMOS Setup and some operating systems such as DOS
can use this console for user interaction.
Console redirection settings are configured on the Features tab of CMOS Setup. The default
setting (On Remote User Detect) causes the console not to be redirected to COM1 unless a signal
(a Ctrl-C character) is detected from the terminal. Console redirection can also be set to Always
or Never. You can direct console output to any COM port.
Notes on console redirection:
When console redirection is enabled, you can access CMOS Setup by typing Ctrl-C.
The decision to redirect the console is made early in BIOS execution and cannot be
changed later.
The redirected console uses 115200 baud, 8 data bits, 1 stop bit, no parity, and no flow
control.
