Dialcodes - Contains the initial digits of telephone numbers
used to establish remote connections over a telephone
line
/usr/lib/uucp/Dialcodes
The /usr/lib/uucp/Dialcodes file contains the initial digits
of telephone numbers used by the uucp program to
establish remote connections over a telephone line. The
Dialcodes file simplifies entries in the
/usr/lib/uucp/Systems file for sites where a number of
device telephone numbers have the same prefix. If users at
your site communicate regularly by way of telephone lines
and modems to multiple systems all located at the same
remote site, or to multiple systems located at different
remote sites, use dial-code abbreviations in the
/usr/lib/uucp/Systems file rather than entering the complete
telephone number of each remote modem in that file.
The Dialcodes file contains dial-code abbreviations and
partial telephone numbers that complete the telephone
entries in the /usr/lib/uucp/Systems file. Entries in the
Dialcodes file contain an alphabetic prefix attached to a
partial telephone number that may include the following
information, in the order listed: Codes for an outside
line. Long-distance access codes (1 and the area code, if
the modem is out of the local area). The 3-digit exchange
number. The relevant alphabetic prefix (representing the
partial telephone number), together with the remaining
four digits of that number, is then entered in the Phone
field in the /usr/lib/uucp/Systems file.
Following is the form of an entry in a Dialcodes file:
DialCodeAbbreviation DialingSequence
The DialCodeAbbreviation part of the entry is an alphabetic
prefix containing up to eight letters, established
when setting up the dial-code listing.
The DialingSequence comprises all the digits in the number
that precede the actual 4-digit telephone number.
Note that if your site uses only a relatively small number
of telephone connections to remote systems, include the
complete telephone numbers of the remote modems in the
/usr/lib/uucp/Systems file rather than using dial-code
abbreviations.
Enter each prefix only once in the Dialcodes file. When
you have set up a dial-code abbreviation, use that prefix
in all relevant entries in the /usr/lib/uucp/Systems file.
Only someone with superuser authority can edit the Dialcodes
file, which is owned by the uucp program login ID.
The Dialcodes file on system venus contains the following
dial-code prefix for use with a number in the
/usr/lib/uucp/Systems file:
local 9=555
The Systems file on system venus contains the following
entry for system zeus, including a telephone number and a
dial-code prefix:
zeus Any ACU 1200 local1212 in:--in: nuucp word: thunder
When the uucp program on system venus dials system zeus,
it uses the expanded telephone number =5551212.
Contains all the configuration files for the uucp program,

available devices Specifies initial handshaking on a connection
