- MS-DOS has the ability to "erase" a line when Cntl-U is typed, and to
- erase the last word on a line when Cntl-W is typed. In PC-DOS and many
- versions of MS-DOS this feature has been disabled by NOPing some of the
- instructions. Since this feature is familiar to UNIX, VMS, and
- mainframe users, there have been messages on ARPAnet, USEnet, and half
- the BBS systems in the free world giving the patches for various flavors
- of DOS.
-
- This is my attempt at the ultimate patch. It doesn't modify the disk
- file, it patches the code in memory, and can be called from the
- AUTOEXEC.BAT file. This makes it impossible to forget to keep an
- unpatched version around. It works on PC-DOS 3.0, 3.1, 3.2, and the
- notorious 3.21 as well. I tried it on four 3.x versions of MS-DOS and
- it worked on them as well.
-
- To enable the control characters, execute the command CTLENABL by hand
- or in a batch file. I have included this documentation, the command
- file, and the source for the paranoid or curious. Please distribute the
- whole package as widely as possible to cut down on the disk space and
- phone time being wasted on this problem.
-
- For those who have MASM and LINK but have never used them, I have
- included a batch file called MAKEFILE.BAT which generates the command
- file and cleans up the mess it makes.
-
- DISCLAMER: use this software at your own risk. (1) it patches your
- operating system, (2) it may not work with some version of DOS, present
- or future, (3) it has not been tested with DOS 2.x, I can't run it on an
- AT and I'm never going back. My liability shall be limited to refunding
- what you paid me for this program (nothing).
-
- Enjoy!
