Dialcodes(4) Kernel Interfaces Manual Dialcodes(4) NAME Dialcodes - Contains the initial digits of telephone numbers used to 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 lo- cated 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 in- clude the following information, in the order listed: Codes for an out- side line. Long-distance access codes (1 and the area code, if the mo- dem is out of the local area). The 3-digit exchange number. The rele- vant alphabetic prefix (representing the partial telephone number), to- gether 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: DialCodeAbbrevi- ation 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 us- ing 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.
