Routers and switches can be part of a LAN, and will be completely
transparent to the data stream (assuming your data gets there at all :-)
X.25 PADs, Analog Modems, and other "serial" components are not in my
definition of a Local Area Network.
Before there were LANs and other sorts of "networks", we had what most
of us just referred to as "datacomm", which involved one or more serial
analog links, with their associated analog modems and serial interfaces
often "implementing" Recommended Standard #232, which described not much
more than a couple of voltages (on a good day).
The difference between a "network" and "datacomm" is that sometimes a
network will actually work the first time you try it.
