Hello I would like to report a bug which I have been unable to trace and / or debug further.
When I do the following in tcsh, "Hello." isn't echoed to stdout and sending an end of file marker exits cat(1), as expected: % cat > /dev/null Hello.^M ^D % but if I do the same inside of GNU screen (version 4.09.1 20-Aug-23, or any other version), then the following happens: % cat > /dev/null Hello.^M Hello. ^D ..."Hello." is echoed to stdout when I press [RETURN], and ^D is printed as a literal caret followed by an uppercase D instead of being interpreted as an end of file marker. This behavior is consistent: - on Solaris 10 i86pc; - on Solaris 10 sparc; - in any shell; - irrespective of which version of screen I've tried to compile and run; - irrespective of compiler used (tried with Sun Studio 12.6 and GCC 9.5.0); - irrespective of whether screen is linked with /lib/64/libcurses.so.1 (AT&T curses) or my own version of libncurses.so.6. stty(1) settings have no effect.
