let's assume I have two boxes, both running some (any) unix variant. I have root privileges on both boxes and they are networked together. I'm using A, the other is B.
I'd like to "mount" the ports for the second computer onto the one I'm currently working on. Thus, A has one serial port locally (/dev/ttyS0), and I'd like to mount the serial port on B locally as say /dev/ttyS1. Or mount the remote parallel port as it was local the same way. Or make an USB "extension cable" by mounting the remote USB ports as local (beyond just plugging in a memory stick and remotely mounting that filesystem)
Maybe I've don't know the magic words to use to research this topic, but from what I can tell, there isn't a general purpose package or program to do exactly this. Or am I wrong?
