I tried the combinations below which do not change anything or are not recognized
\n
\^m
\^Y
Ctrl-V + Ctrl-M
Ctrl-V + Ctrl-Y => nothing is typed in the console, I have to do a Ctrl-C to get out
\x0D$
\xC1$
[^M^Y]
[^M]
[^Y]
\c[m => not recognized
sed 's/.$//' does remove the ^M at the end of each line but then it is still a multi-line format. Its like removing the last character of each line but keeping the end-of-line linefeed.
[added comments]
Is there a way to find out in VI what is the ascii value of the character under the cursor ?
It would help me identify the right decimal value to use in a replacement string.
[added comments]
I found out that ^M is actually \015. So I can remove it with tr -d '\015'
But I still haven't found out what ^Y is.

vbindiff
VBINDIFF(1) Christopher J. Madsen VBINDIFF(1)
NAME
vbindiff - hexadecimal file display and comparison
SYNOPSIS
vbindiff file1 [ file2 ]
DESCRIPTION
Visual Binary Diff (VBinDiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight
the differences between them. Unlike diff, it works well with large files (up to 4 GB).
Viewing files
Movement Keys
-------------
Up Move one line (16 bytes) towards the beginning of the file
Down Move one line (16 bytes) towards the end of the file
Left Move one byte towards the beginning of the file
Right Move one byte towards the end of the file
PageUp Move one page towards the beginning of the file
PageDn Move one page towards the end of the file
Home Move to the beginning of the file
End Move to the end of the (shorter) file
F Search for a string or byte sequence
G Move to a specified file position
When displaying two files, both files move together. If bytes have been added or removed in one of the files, you can adjust the compari-
son by moving just one of the files. To move only the top file, press "T". To move only the bottom file, press "B". To return to moving
both files, press the same key again. (The window at the bottom of the screen will indicate when you are moving only one file.)
Other Keys
----------
Enter Move to the next difference between the files
Space (same as Enter)
C Toggle between ASCII and EBCDIC display
E Edit currently displayed section of file
Esc Exit VBinDiff
Q Exit VBinDiff
The "Enter" key will advance to the next difference between the files (after those already displayed on the screen). If there are no more
differences, it moves to the end.
Line editor
The line editor is used to enter search strings and file positions. It uses the basic Emacs-style editing keys.
Keys
-----------------
Ctrl-B, Left Move the cursor one character left
Ctrl-F, Right Move the cursor one character right
Ctrl-A, Home Move to the beginning of the line
Ctrl-E, End Move to the end of the line
Ctrl-P, Up Move up in input history
Ctrl-N, Down Move down in input history
Ctrl-H, Backspace Delete the character to the left
Ctrl-D, Delete Delete the character under the cursor
Ctrl-K Delete from cursor to end of line
Insert Toggle between insert & overstrike mode
Enter Finished entering text
Esc Abort the operation
Editing files
You can press "E" to edit the current file. When displaying two files, this edits the one in the top window, unless you are in "move bot-
tom" mode.
When editing, you can move the cursor around with the arrow keys. Use TAB to switch between entering hexadecimal or ASCII (or EBCDIC)
characters. Press the Esc key when you are done. You will be given the choice to save or discard your changes then.
If you are displaying two files, you can use the Enter key to copy a byte from the other file into the one you are editing.
You cannot scroll through the file while editing, although you can save your changes and then move to a different part of the file. Also,
you cannot insert or delete bytes, only change them.
OPTIONS
-L, --license Display license information for vbindiff
-V, --version Display the version number
--help Display help information
BUGS
Does not work properly with files over 4 gigabytes. It should be able to view the first 4 gigabytes ok, but the display only has room for
8 hex digits of file position, and the Goto box is also limited to 8 digits.
