Network Technology -- Point-to-Point Data Links
These are the most basic data communications links, eg:

Virtually all computers support such data links, using their
so-called serial ports. Typically, these ports are
able to operate at any standard bit rate between 300 bps and 230400
bps.
The most common hardware interface standard used in such data
links is called RS232: in fact, the term RS232
port is widely used as a synonym for serial
port.
A connection may be "direct" or may use a
modem.
