SUMMARY
=======
You can use the ANSI.SYS device driver to disable the CTRL+C key combination.
This is done by assigning the CTRL+C key combination to NULL.
NOTE: ANSI.SYS must be loaded in the CONFIG.SYS file to enable ANSI escape
sequences.
MORE INFORMATION
================
To disable the CTRL+C key combination, create a file using the following steps:
1. Run MS-DOS Editor.
2. Type the following on the same line with no spaces between:
" CTRL+P 027 " (without the quotation marks)
To type this line, hold down the CTRL and P keys simultaneously and then
release them. Then hold down the ALT key while you press the 0, 2, and 7 keys
on the numeric keypad.
These key combinations produce the left arrow that symbolizes the start of the
ANSI escape sequence.
3. On the same line, leaving no spaces, type:
" [3;0;p " (without the quotation marks)
4. Save this file as a batch file (for example, FILE.BAT).
5. Exit MS-DOS Editor.
Type the following at the MS-DOS command prompt to disable CTRL+C:
" type file.bat " (without the quotation marks)
To enable the CTRL+C key combination, replace step 3 above with the following
" [3;3p " (without the quotation marks)
and save the file under a different name.
By adding the TYPE command and the name of the file to the AUTOEXEC.BAT file, you
can disable or enable the CTRL+C key combination when the machine starts up.
