1  PHONE
   Invokes the OpenVMS Phone utility (PHONE). The Phone utility is
   designed to simulate some of the features of actual telephone
   communications. You can use the Phone utility to communicate with
   other users on your system or with any other system connected to
   your system by DECnet for OpenVMS. To invoke the Phone utility,
   enter the PHONE command at the DCL prompt and press RETURN.

   When entering the DCL command PHONE, you can supply qualifiers
   that modify the characteristics of the simulated telephone.

   Format

     PHONE  [phone-command]
 

2  Parameter
 

phone command

   Specifies an optional Phone utility command that enables you to
   control your phone conversation. You can specify a PHONE command
   parameter as part of the PHONE command line, or you can enter one
   at any time during the phone conversation by typing the switch
   hook character (%) and the desired command. The following list
   summarizes the functions of each Phone utility command:

   ANSWER      Answers the phone when you receive a call.
   DIAL        Places a call to another user.
   DIRECTORY   Displays a list of the users you can call.
   EXIT        Exits from the Phone utility.
   FACSIMILE   Includes the contents of a file in your conversation.
   HANGUP      Cancels the current phone call.
   HELP        Displays information on how to use the Phone utility.
   HOLD        Places the other users in a call on hold.
   MAIL        Sends a message to another user.
   PHONE       Places a call to another user.
   REJECT      Rejects a call from another user.
   UNHOLD      Reverses the previous HOLD command.

   For a detailed description of each Phone utility command, invoke
   the Phone utilty and type HELP at the switch-hook prompt.
 

2  Qualifiers
 

/SCROLL

      /SCROLL
      /NOSCROLL

   Determines how new lines of text are displayed on the screen
   when the viewport becomes full. If /NOSCROLL is specified, the
   text lines are wrapped and new text appears on the top line of
   the viewport. /NOSCROLL improves the response time for terminals
   operating at slow speeds.

   If /SCROLL is specified, the text is scrolled up one line each
   time a new line of text is entered. The new line appears at the
   bottom of the viewport. /SCROLL is the default.
 

/SWITCH_HOOK

      /SWITCH_HOOK="character"

   Specifies the Phone Utility switch-hook character (%).  The
   switch-hook character must be entered before each Phone utility
   command that is entered during a conversation.

   PHONE commands are terminated by pressing RETURN or by entering
   the switch-hook character. Text typed without the switch-hook
   character is considered part of the conversation. You can use
   any nonalphanumeric character as the switch-hook character.
   Enclose the character in quotation marks. The default switch-hook
   character is the percent sign (%).
 

/VIEWPORT_SIZE

      /VIEWPORT_SIZE=n

   Specifies the maximum number of lines in a viewport, including
   the heading line and the bottom line of dashes. The valid range
   is 3 to 10 lines. Smaller viewports will improve the response
   time on terminals operating at slow speeds. The default viewport
   size is automatically reduced as more participants enter the
   conversation.
 

2  Examples

   1.$ PHONE

     The DCL command PHONE invokes the Phone utility. If you issue
     the PHONE command without qualifiers or parameters, the Phone
     utility prompts you for the name of the person you want to
     call (or any other PHONE command) with the default switch hook
     character, the percent sign. The Phone utility also displays
     the title "VMS Phone Facility", and the date, and sets up your
     viewport.

   2.$ PHONE ANSWER

     Use this command to answer a call.

   3.$ PHONE DIRECTORY TAMPA::

     The PHONE command causes the Phone utility to display a
     directory of users available on node TAMPA.

   4.$ PHONE /SWITCH_HOOK="\" /VIEWPORT_SIZE=5  EUGENE::MALCOLM

     The PHONE command defines the SWITCH_HOOK character to be the
     backslash (\), restricts the VIEWPORT_SIZE to five lines, and
     places a call to user MALCOLM on node EUGENE.
