 With the new "libteken" terminal emulator code in 9-current, syscons is
 now much like xterm. It appears that Backspace is still ^H, but Delete
 is now ^[[3~ instead of ^?.
 
 A while ago, I changed 9-current libedit (and therefore programs like sh
 and ftp) to recognize ^[[3~. I encourage you to ask tcsh upstream to fix
 this as well (either by hardcoding ^[[3~ somewhere or by using the
 appropriate termcap/terminfo field).
 
 Making the Backspace key send ^? may be slightly dangerous as it is
 rather annoying if Backspace does Delete (more annoying than Delete
 doing Backspace, IMHO). On the other hand, vte-based terminal programs
 such as gnome-terminal and xfce4's Terminal send ^? by default and it
 seems to work fine.
