Unfortunately, cygwin's terminfo/termcap entries for XTERM say that the
backspace key returns ^H.
xterm does still send ^H, but I agree both xterm and its termcap entry
ought to be changed to match the new Cygwin 1.7 default and the Linux
world. I should have a look at how to do that.
Well, on Linux consoles, the term type is "linux". Presumably this is
one of the reasons they felt they needed a separate term type.
Maybe MinTTY should be emulating something other than xterm, which
doesn't have this backspace problem? I don't mean something vastly
different, just something else in the ANSI/VT100 zoo.
Have you come across an application that stumbles over this?
Obviously you're responding to some user reported bug, so here's a
better question: how does Emacs handle C-h on Linux under xterm? If it
works fine, you should try to find out how xterm manages that.
All the
one's I've tried seemed to go by the stty setting rather than the
termcap entry anyway.
This is a problem I still see on Linux today. Programs that accept user
input via standard C mechanisms (rather than something intelligent like
ncurses) often don't deal with regular backspaces. So, test with things
like ftp or ex. Or, write a simple test program that uses gets() or
similar. If that handles backspace correctly, that's a high endorsement
for doing it the way you are already.
