Ponder, I haven't followed this much at all, but a 286 12Mhz+ ought to be
able to push 19.2k on an 8250/16450 with no fuss.

I started this reply before noticing that you'd swapped TCPser out for
something else.  You'll need to keep in mind that any serial/tcp conversion
is going to add latency to the stream.  So does any port extra port
forwarding. I have this kind of problem on TLP. I'm using RLFOSSIL for the
serial/tcp conversion, and I have inboard port forwarding to make each node
active off one outside port, which has already been forwarded to the system
with node selection on it.  Even running all of this on the same system adds
significant overheard.

I believe all that gets in the way of ANSI detection, involving some escape
sequence, it fails 50-75% of the time.  Also stops file transfers in their
tracks too.
