That has nothing at all to do with the kernel; it's in the

$ stty erase X

Oh, what is
the deal with backspace/delete? Backspace does
nothing, whilst
delete echos some form of control code to the screen. ctrl-H seems
to work
as the erase character, though (and genuinely does erase from the
string
that gets sent to the server upon <return>). Is the PCjr doing
something
non-standard with the handling of such keys, or is it just that other
telnet servers generally hack such keypress processing to accommodate
modern clients?
Well, the Linux kernel expects the erase key to be ASCII 127, and
has the
backspace key generate said character. The default xterm expects
the erase
key to be ASCII 8 and doesn't know how to handle ASCII 127 that the
backspace key under Linux sends. And it drives me nuts!
