You really don't need to modify the kernel to do what you wish.
What you seem to want is a T(W)ENEX-style shell that runs in
RAW or CBREAK mode, so that it can process each character as it
is typed.

There is no need to invent this capability again.  I'm running a very
sophisticated version of the CSH which is called TCSH (TWENEX CSH) --
you can bind functions to keys, or to key sequences, has command and
file name completion, EMACS-style history editing, etc, etc.
If you have a UNIX source license, contact <phil@brl.arpa> to arrange
for a copy.

If you prefer Bourne shell over CSH, no sweat.  A similar set of
features has been added to the Bourne shell, which is now called TBSH
(TWENEX Bourne SHell).  If you have a System-V R2 source license,
contact <dpk@brl.arpa> to arrange for a copy.
	Best,
