I am convinced, as I have been for quite some time, that the right way
to do this is with USB serial adapters.  That way, you can run *one* cable
to a rack of machines, split things out with USB hubs on the rack, and have
a clean, inexpensive solution that even does DMA at the host end.

You're allowed to chain up to three USB hubs.  That should get you a *huge*
number of ttys even using a single host USB controller with its two ports;
of course, most new motherboards have two USB controllers, and four ports...
