establish remote connections over a telephone line
SYNOPSIS
/usr/lib/uucp/Dialcodes
DESCRIPTION
The /usr/lib/uucp/Dialcodes file contains the initial digits of tele‐
phone 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 regu‐
larly by way of telephone lines and modems to multiple systems all
located at the same remote site, or to multiple systems located at dif‐
ferent 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 tele‐
phone 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 con‐
taining 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.
EXAMPLES
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 sys‐
tem 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.
