I never had any joy with TCPser on anything.  I was able to get a functional
result by using a Raspi as a pad, serial to it, and telnet from there.

I'm a little perplexed that disabling terminal options appears to improve
performance. It would be saying to me that either the serial work isn't well
optimised or the whole thing is to much for the grunt of the system you're
driving it with.

 ki> for dos. I've got telix and terminate downloaded somewhere to also play

If I recall correctly Telemate has direct support for 16550s.  I do recall
problems with Telix at higher speeds later on, not sure if it was handshaking
problems or something else. But it was showing its age and not getting
updates.

 ki> I've not been able to get anything over 19.2k to work reliably so far & I

19.2k tends to be the limit for 8250/16450 on anything up to a 286, even the
old 21Mhz wouldn't reliably 38.4.  You'd probably need more horsepower.
16550A may improve things, but it wasn't really aimed at slow machines, it
was aimed at faster systems where the actual interrupt service time was
shorter. So it could dump what it had in a short time.
