The rtermios default setting will need to change accordingly,
either by changing the definition of CERASE in include/sys/termios.h:
-#define CERASE CTRL('H')
+#define CERASE CDEL
Or by changing the initialisation in fhandler_termios.c:
- tc->ti.c_cc[VERASE] = CERASE;
+ tc->ti.c_cc[VERASE] = CDEL;
The cygwin section in /etc/termcap doesn't have a kb entry, so luckily
no change needed there.
terminfo has an entry for backspace though:
$ tput -T cygwin kbs | cat -v
^H
So this has to to change as well:
+++ terminfo.src 2009-05-30 07:50:44.893933600 +0100
@@ -5221,7 +5221,7 @@
- kbs=^H, kcub1=\E[D, kcud1=\E[B, kcuf1=\E[C, kcuu1=\E[A,
+ kbs=^?, kcub1=\E[D, kcud1=\E[B, kcuf1=\E[C, kcuu1=\E[A,
And then there are rxvt and xterm and their termcap and terminfo
entries as well ...
