3.4.7 - Connecting a USB-RS232 Adaptor
a) Overview
A USB-RS232 adaptor is normally a cable with USB connector at one end and
one or more serial connectors (DB9 or DB25) at the other end. This allows
serial devices to be connected when no more native serial ports are available.
This technology is sometimes embedded in USB devices. For example touch
screens or card readers. These devices have a USB connector but are based
on serial technology and are seen as serial ports.
