  Dialcodes - Contains the initial digits of telephone numbers used to estab-
  lish remote connections over a telephone line




  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:

   1.  Codes for an outside line.

   2.  Long-distance access codes (1 and the area code,	if the modem is	out
       of the local area).

   3.  The 3-digit exchange number.  The relevant alphabetic prefix
       (representing the partial telephone number), together with the remain-
       ing 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 contain-
  ing 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.

	    including the Dialcoddes file

	    Contains information about available devices

	    Specifies initial handshaking on a connection

	    Describes accessible remote	systems
