There has been much mail on the topic of patching various DOS'es to enable
control-U and control-W support.  No one has provided specific instructions
at the byte-location level of detail.

I was able to compare the IBMDOS.COM file in PC-DOS 3.1 with the corresponding
files for Xerox MS-DOS 3.1 and Wyse MS-DOS 3.1.  No two files are alike, but
the latter two both support control-U and -W.

Presumably, I would have to use a disk sector editor, such as Norton, because
I have to be sure not to move the location of IBMDOS.COM on the disk.

Any suggestions.  Please post directly to the net, for the benefit of all.
