  .  Description

  The _dialpref system variable holds the string which should be sent
  to the modem before the number, when dialing. For Hayes type modems,
  it is usually set to "ATDT". Maximum length is 19 characters. This
  string will possibly include translation characters, as described in
  the Telix manual, and should be sent to the modem with the cputs_tr
  function.

  The _dialpref2 and _dialpref3 are the other two dialing prefixes
  that may be defined in Telix.
