1 CALLOUT
.BR
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.
.S 1
The format of the CALLOUT command is:
.S 1
.I 4
_$ CALLOUT[/qualifiers] terminal-device-name
.S 1
.I -1
2 Command__definition
.BR
The CALLOUT command must be defined prior to use.  Use
.S 1

_$ SET COMMAND PRIV:CALLOUT

2 Commands
.BR
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:
.SK 1
.I 4
Callout [system__name]>
.SK 1
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:
.SK 1
.LM +4
HELP#########Lists valid commands.
.BR
SPAWN########Spawn a DCL subprocess.
.BR
INTERRUPT#n##Change ASCII value of interrupt character to n.
.BR
SEND######n##Send character with ASCII value n.
.BR
EXIT#########Exit the program.

2 Parameter
.BR
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
.I -1
/INTERRUPT=n
.BR
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.
.SK 1
The default for this qualifier is /INTERRUPT=1, the ASCII value for
control-A (_^A).
.SK 1
.I -1
/SPEED=n
.BR
Specifies the baud rate of the outgoing terminal line.  This must be
a legal baud rate.
.SK 1
The default for this qualifier is /SPEED=1200.
.SK 1
.I -1
/ECHO
.BR
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.
.SK 1
The default for this qualifier is /NOECHO, indicating that characters
typed are not to be echoed locally.
