Normally you can emit <DEL> to erase the character immediately to the left of
the cursor. Backspace (<BS>) might also do the trick as long as you overwrite.

If you find a vt manual from Digital you may find a lot of interesting codes to
use. E.g. you can get a report on where the cursor is. The only problem with
that is that not everybody have done it as good as Digital (e.g. they only
supprot <ESC>[ instead of <CSI>).

If you keep track of where the cursor is on the screen it should be no problem
going back.
