In a recent article to this newsgroup it was stated that the
(hardwired) driver for the Ann Arbor Ambassador in the emacs code of
Gosling has problems at > 4800 bauds, because of insufficient padding.
In my experience, the opposite is true: the padding is not necessary at
all. I took it out everywhere, except for the "redraw screen" command,
where it is really needed. The insert/delete-char/line commands do not
need any padding at all.
I am running (under unix) at 9600 bauds, using an Able multiplexer.
Could this last be the reason why I do not seem to need padding?info-vax (12/22/82)

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!

CurrentMode, DesiredMode;
should read:

DesiredMode;

of this text was released. The mailer jumped before I could
