UUCP is derived from Unix-to-Unix copy. It is a standard UNIX utility that manages the transmission of information between UNIX systems, using serial connections and regular telephone lines. The Communications package was developed at Bell Laboratory by Mile Lesk in the mid-1970s for serial communications between in-house UNIX systems.
It was revised in 1978 and again revised in the early 1980s. This version became known as HoneyBer UUCP. A newer version, known as Taylor UUCP is also available on some systems, particularly Linux. UUCP provides the following:
File transfer between two hosts.
A communication protocol for e-mail and USE-NET groups.
Control of communications devices.
A set of utilities for managing the UUCP package.
UUCP is usually set up by a system administrator. The configuration of UUCP consists of;
Telling your system what kind of modems you have on your computer and where they are located.
Describing how to talk to these modems.
Listing all the other systems that you would like to connect with, along with their phone numbers and passwords.
UUCP networks are found throughout the world and continue to perform important functions, connecting users who cannot access the Internet directly. Because UUCP is available on all sorts of systems, many other applications have been made compatible with it.
