Placing the Call
................

`speed NUMBER'
`baud NUMBER'
     Specify the speed (the term "baud" is technically incorrect, but
     widely understood) at which to call the system.  This will try all
     available ports with that speed until an unlocked port is found.
     The ports are defined in the port file.  If both `speed' and
     `port' commands appear, both are used when selecting a port.  To
     allow calls at more than one speed, the `alternate' command must be
     used (see Defaults and Alternates.).  If this command does not
     appear, there is no default; the speed may be specified in the port
     file, but if it is not then the natural speed of the port will be
     used (whatever that means on the system).  Specifying an explicit
     speed of 0 will request the natural speed of the port (whatever
     the system sets it to), overriding any default speed from the
     defaults at the top of the file.

`port STRING'
     Name a particular port or type of port to use when calling the
     system.  The information for this port is obtained from the port
     file.  If this command does not appear, there is no default; a
     port must somehow be specified in order to call out (it may be
     specified implicitly using the `speed' command or explicitly using
     the next version of `port').  There may be many ports with the
     same name; each will be tried in turn until an unlocked one is
     found which matches the desired speed.

`port STRING ...'
     If more than one string follows the `port' command, the strings are
     treated as a command that might appear in the port file (
see port File.).  If a port is named (by using a single string
     following `port') these commands are ignored; their purpose is to
     permit defining the port completely in the system file rather than
     always requiring entries in two different files.  In order to call
     out, a port must be specified using some version of the `port'
     command, or by using the `speed' command to select ports from the
     port file.

`phone STRING'
`address STRING'
     Give a phone number to call (when using a modem port) or a remote
     host to contact (when using a TCP or TLI port).  The commands
     `phone' and `address' are equivalent; the duplication is intended
     to provide a mnemonic choice depending on the type of port in use.

     When used with a modem port, an `=' character in the phone number
     means to wait for a secondary dial tone (although only some modems
     support this); a `-' character means to pause while dialing for 1
     second (again, only some modems support this).  If the system has
     more than one phone number, each one must appear in a different
     alternate.  The `phone' command must appear in order to call out
     on a modem; there is no default.

     When used with a TCP port, the string names the host to contact.
     It may be a domain name or a numeric Internet address.  If no
     address is specified, the system name is used.

     When used with a TLI port, the string is treated as though it were
     an expect string in a chat script, allowing the use of escape
     characters (see Chat Scripts.).  The `dialer-sequence' command
     in the port file may override this address (see port File.).

     When used with a port that not a modem or TCP or TLI, this command
     is ignored.
