 Name

    systems - format of UUCP Systems file

 Description

    The Systems file (/usr/lib/uucp/Systems) contains the information needed
    by the uucico daemon to establish a communication link to a remote com-
    puter.  Each entry in the file represents a computer that your computer
    can call.  You can configure the Systems file to prevent unauthorized
    computers from logging in on your computer. More than one entry may be
    present for a particular computer.  These additional entries represent
    alternative communication paths which the computer tries in sequential
    order.

    Each entry in the Systems file has the following format:

       sitename  schedule  device  speed  phone  login-script


    sitename       the node name of the remote computer.

    schedule       a string that indicates the day-of-week and time-of-day
                   when the remote computer can be called.

    device         the device type that should be used to establish the com-
                   munication link to the remote computer.

    speed          the transfer speed of the device used in establishing the
                   communication link.

    phone          the phone number of the remote computer for automatic
                   dialers.  If you wish to create a portable Systems file
                   that can be used at a number of sites where the dialing
                   prefixes differ, see the dialcodes(F) man page.

    login-script   login information (also known as a ``chat script'').
