Bill, you sure have a lot of nightmares where others just have have sweet
dreams - perhaps you should lay off the late night stacks. The single port
adapters will use ONE DRIVER and cost less than the multi-port units. (At
least, they cost much less, about 1/2 as much per port, than the multi-port
units offered by Byterunner.)

In any event, Dan Lanciani's ethernet-serial suggestion, since it only needs
one ethernet port, is probably the easiest way to go if you can find a cheap
used unit. I don't usually recommend eBay because I prefer to look my fence
in the eye when he tells me, "It fell off a truck". ;)
