(Xubunto 16.04).  I’ve got this working *pretty* well, but it looks like
the padding values in the default vt100 terminfo entry are not quite
correct — when running the vt100 at 9600 I still get occasional garbage
characters on the screen, and 19200 is a hopeless mess.

padding values in the terminfo are disregarded.  Removing this, then
disabling xon/xoff on both the vt100 and the tty device actually produces
*better* results — apparently the turnaround on xon/xoff isn’t quite fast
enough to keep the terminal from being swamped at higher baud rates, and
padding actually works better.  But tracking down the source for the
default vt100 entry turned up a comment that admits that the padding values
there are a total guess. :-(

Even better, I found this post, this is my how to attach a vt100 to a VAX
4000, you can apply to most any case
