Look at the MDSN
documentation about ASCII
characters: ASCII Character Codes Chart 1
They state: "ASCII code 127 has the code DEL. Under MS-DOS this code has the same effect as ASCII 8 (BS). The DEL code can be generated by the CTRL + BKSP key."
I tried your code on my computer (Windows Vista 32 bit
), and I found this:
- the BACKSPACE key produce the code 8;
- the DELETE key produce the code 224;
- the CTRL + BACKSPACE key produce the code 127.
