 |Hi,

 |Where are those characters lost to (or thrown away) that are typed in?

They are likely discarded in a mode-switch drain?
I once had an user report which, granted, is userspace, fix was

  +                  /* As a special case, simulate EOF via EOT (which can happen
  +                   * via type-ahead as when typing "yes\n^@" during sleep of
  +                   *    $ sleep 5; mail -s byjove $LOGNAME */
  +                  if(*cbufp == '\0' && (n_psonce & n_PSO_INTERACTIVE) &&
  +                        !(n_pstate & n_PS_ROBOT))
  +                     *cbuf = '\x04';

 |Anyone any ideas?

Other than that not.
