I have noticed that if you exceed 64 characters on a serial login
using getty that when you go to backspace and hit the 64 character
mark that the cursor automatically jumps up one line.  Why is this?
If you have a long command and want to modify something on it, it
becomes pretty hard when you backspace beyond the 64'th character
since your cursor is one line above the text you are trying to edit.

My system is a PXA270 running busybox 1.2.1 I know that is a pretty
old version of busybox but I have spoken with several other developers
using different hardware and newer versions of busybox and they have
seen the same issue.   I have not tried it on a system not running
busybox so I can't say for sure that it is something specific to
busybox.  If somebody  knows way this happens I would love to hear
about it.
Regards,
Shane
