I have a system that uses com3 "ttyS2" (0x3E8, irq 5) for console redirection,
and when trying to boot DOS from (Hard drive or image) over IPMI, nothing is
being to return to the IPMI and is being sent to console.

Booting the Hard drive or image (over pxe) works fine over IPMI. Grub display
fine over IPMI, but when booting Dos or having grub exit so the next hard
drive boot, console redirection is lost.

Here is where it starts to get strange. These are the settings I thought
should work, but don't. 

I have tried setting terminal_(input/output) to the following settings
("serial console", "serial_com2 serial console"), but neither worked. This has
also brought up another bug where grub-mkconfig doesn't accept serial_comX as
a valid setting in $GRUB_TERMINAL_OUTPUT.

I was able to actually get console direction to work correctly, by adding
serial_comX ( Where X is 3 or higher ) into terminal_(input/output). 

This is currently still an issue with the latest copy of code in the git repo.
