(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.

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. :-(

I thought I’d ask if anybody has a good vt100 entry already on hand?  (I’d
take one for the VT52 as well!)

Post the relevant inittab line for ttyUSB0, assuming you are using a USB to
Serial adapter, we can troubleshoot
