oder:   xdial

Beispiel: Sie geben ein 'dial 08912345'.
Darauf hin sendet Dial 'atdt008912345,,!,,31,,;H\\r' an das Modem.
Wenn die Verbindung besteht, dann wird über die Telefonanlage auf die
Nebenstelle 31 weitervermittelt.

xdial sucht selbst nach $DefaultTelefonBuch als Telefonbuch.
Das Telefonbuch ist zeilenweise so aufgebaut:
Nummer : Name
Nummer : Name
Nummer : Name
