Actually Cygwin 1.7 defaults to ^? no matter the Windows version. Cygwin 1.5 used ^H. > which is > preserved on ssh to Linux where backspace works in vi and in SQLPlus. > > In Windows 7 Professional erase defaults to ^?

Perhaps have another look through the relevant shell startup files on the Linux side, including the global ones in /etc. You are using Cygwin ssh, right? > And doing stty erase '^?'

Which probably means that either SQLPlus is fixed to ^H or it relies on terminfo, whereas ideally it should pay attention to the 'stty erase' setting. You could confirm this by finding a TERM setting that has ^? in the kbs terminfo capability, e.g. using tput: $ TERM=xterm tput kbs | cat -v ^? Then try SQLPlus with that TERM setting. Note, however, that using the Cygwin console (or any terminal) with an incompatible TERM setting might cause other problems. > I upgraded from Cygwin 1.5.25 to 1.7.9 based on 1.7.2 release notes > stating the console's backspace keycode can be changed using 'stty > erase' but no change. Yeah, that turned out to be a bad idea, because some programs set the erase character to NUL to disable it, which meant that the backspace key sent NUL. Hence in 1.7.5 this was replaced with support for the "DEC Backarrow Key Mode" (DECBKM) control sequence, which can be used like this: for ^H: echo -ne '\e[?67h' for ^?: echo -ne '\e[?67l' You'll still want to set 'stty erase' accordingly though. You might also want to have a look at the mintty terminal, which uses TERM=xterm, so things might work out-of-the-box. Otherwise, there's a config dialog option for switching to ^H, which changes both the backspace keycode and sets the erase character accordingly at startup.
