Subject: [PATCH] kconfig/[mn]conf: handle backspace (^H) key
Date: Mon, 25 Mar 2019 15:16:47 +0000 [thread overview]
Message-ID: <20190325151647.11581-1-changbin.du@gmail.com> (raw)
Backspace is not working on some terminal emulators which do not send the
key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127).
But currently only '$?' is handled. Let's also handle '^H' for those
terminals.
