  Since it came up again, I thought I would mention that there is
 a bug in the terminal driver for Unix Emacs (Gosling), which is
 responsible, in part, for some of the problems. The bug is in
 TrmAmb.c in the function "blanks". The old code was:

    SetHL(0);
    if (CurrentMode == m_insert) {
        printf ("\033[%d@", n);

  etc.

  It should read:

    SetHL(0);
    if (DesiredMode == m_insert) {
        printf ("\033[%d@", n);

  We have found that this seems to solve the problems sometimes
  attributed to padding, at speads in excess of 9600 baud. This
  error was in a version of Emacs which we got in July so later
  editions may have fixed this.

  Merry Christmas!
