}But dumb ports (multple ones) supporting high speed modems put a massive
}load on the primary CPU (don't they?)
}

On Xenix even using 16450's will work for one or two Trailblazers quite
nicely. On my system (25Mhz 386) I didn't really notice a tremendous load.

With 16550's I have run three Trailblazers and three 2400 Hayes with little
loading and no character loss problems.
