Limitations
Console redirection is a real-mode BIOS extension. It does not operate outside of real mode. In
addition, console redirection will not function if the OS or a driver, such as EMM386*, takes the
processor into protected mode. If an application moves the processor in and out of protected
mode, it should inhibit redirection before entering protected mode and restart redirection when it
returns to real mode.
Scanning and sending changes in text video memory redirect video. Therefore, console
redirection is unable to redirect video in graphics mode. Since the BIOS scans the text video
memory, an additional limitation exists if the system does not contain a video graphics adapter or
a proprietary means of buffering the video memory. The BIOS may not have a method to send
changes in text video memory if an application such as an option ROM writes directly to video
memory.
Phoenix* BIOS uses the serial port interrupt to send the Video RAM data to remote console and
receive the remote input. When the data receive from the Remote site by serial port, it will be put
into the KB buffer by int16 to simulate it comes from the local KB by INT9.
Software bypasses this handler does not receive redirected keystrokes.

Serial Ports
The SE7500CW2 server board has two serial ports, an internal 9-pin header for COM2, and an
external COM1 serial port that can be used. Refer to sections 3.3 and 8.13 for additional serial
port information.
