1 CALLOUT
 The CALLOUT utility is used to  connect  the  user's  current  terminal
 transparently  to  another  terminal  line on the system.  This is most
 useful when the other terminal is a line to another computer system  or
 to  an  outbound,  auto-dial  modem.   In this case, CALLOUT allows any
 terminal on the local system to access another computer system.

 The format of the CALLOUT command is:

     $ CALLOUT[/qualifiers] terminal-device-name

2 Command_definition
 The CALLOUT command must be defined prior to use.  Use

     $ SET COMMAND PRIV:CALLOUT

2 Commands
 The interrupt character, which is control-A  (^A)  by  default,  forces
 CALLOUT into command mode.  Command mode indicates that it is expecting
 a command with a prompt of the form:

     Callout [system_name]>

 where "system_name" is the network  node  name  of  the  host  computer
 running  Callout.   When  the  prompt appears, a single command will be
 accepted and processed.  Current commands are:

     HELP         Lists valid commands.
     SPAWN        Spawn a DCL subprocess.
     INTERRUPT n  Change ASCII value of interrupt character to n.
     SEND      n  Send character with ASCII value n.
     EXIT         Exit the program.

2 Parameter
 The CALLOUT  command  requires  a  single  device  name  as  the  input
 parameter.   The  device  specified  should  be a terminal connected to
 another terminal  port.   For  example,  a  terminal  line  to  another
 computer system or to a modem capable of originating a call.

2 Qualifiers
/INTERRUPT=n
 Specifies the ASCII value of the interrupt character that signals entry
 into  CALLOUT  command  mode.  The "Callout>" prompt will appear, and a
 single command (documented  under  the  "Commands"  subtopic)  will  be
 accepted and processed.

 The default for this qualifier is /INTERRUPT=1,  the  ASCII  value  for
 control-A (^A).

/SPEED=n
 Specifies the baud rate of the outgoing terminal line.  This must be  a
 legal baud rate.

 The default for this qualifier is /SPEED=1200.

/ECHO
 Indicates that characters typed by the user are to be  echoed  locally.
 This  is  useful  when  the  remote system does not support full-duplex
 character echoing.

 The default for this qualifier is /NOECHO, indicating  that  characters
 typed are not to be echoed locally.
