We've been having this problem since 18.54 and VMS 5.  Emacs simply
doesn't seem to be able to keep with fast character input.  I've made
inquiries about this in the past, and received a few suggestions for
patches (though don't remember what they were at the moment), but
nothing seems to help.

The problem manifests itself mostly when Emacs is used via vt tubes
(vt220, 240, 320, etc.) which are connected thru DEC terminal servers.
But, I've seen Emacs dropping keys even when running as an X11 client.
Whenever it drops a key when run under X11 it will issue a beep (so
I notice right away and thus it's not so bad), which makes me wonder
how it "knows" it lost a key, and if it does, why can't it just keep
up.

I always hoped that later versions will correct that.  I see that as
of 18.58 it's still a problem. :-(

Sorry I couldn't be more of a help.

It's probably because Emacs switches the terminal session to passthru
mode, so all characters are passed to it instead of being grabbed by
the terminal server.  To forward session while in Emacs, try hitting
break (which puts you back into local on DEC's servers) and then the
forward-session char.
