Creating a portable UUCP Systems file

Creating a portable UUCP Systems file

The Dialcodes file (/usr/lib/uucp/Dialcodes) contains the dial-code abbreviations that can be used in the ``Phone'' field of the Systems file. This feature is intended primarily for those who wish to create a standard Systems file for distribution among several sites that have different phone systems and area codes. As such, the Dialcodes file is probably not necessary for most sites. See the dialcodes(F) manual page for more information, and ``How UUCP works'' for general background on how the Dialcodes file is used.
