Serial output sent to console

[Steven R. Lilly]

Hello,

I am using GRUB version 0.90 (shipped with RedHat GNU/Linux 7.2). I am
attempting to set up a system that presents the GRUB menu, kernel output,
login prompt, etc. to the serial port instead of the monitor (the system
will eventually have no keyboard or monitor). During the setup process, I
have serial terminal, keyboard, and monitor attached.

I issue the following from the GRUB command line:

serial --unit=0 --speed=38400
terminal serial

GRUB displays this on the console (a.k.a. monitor):

Press any key to continue.
Press any key to continue.
Press any key to continue.
...

*Nothing* is displayed on the serial terminal. However, after I press a key
in my serial terminal, it appears as if GRUB is taking input from the
serial, and displaying the output on the console. No output appears on the
serial terminal.

For example, I type "help" on the serial terminal, and the list of commands
is displayed on the console (instead of the serial terminal).

Any ideas? I'm scratching my head on this one...
