With a little fantasy it's easy to imagine 10 serial devices connected to a
single computer. I once did some work on a modem firmware and had four
(external, of course) modems connected at the same time to the same
computer. Or a couple of bar code readers or any other serial (RS232,
RS485) process devices... It's not all standard desktop apps what one might
do with a PC.
