1 EXIT
Exits from VTERM.
1 HELP
Displays information about VTERM commands.
1 General
VTERM is a 'virtual terminal' handler for VAX/VMS. Once in VTERM,
you are logically connected to the modem as if you were
hard-wired to it.  VTERM has a small number of commands used to
control it's execution. To issue a VTERM command, enter
control-A, which will display the VTERM command prompt <VTERM:>. 
The following terminology is used throughout VTERM documentation:

Local computer - The VAX on which VTERM is run.

Remote computer - The computer to which the remote port is connected.

Local terminal - The terminal (on the local VAX) from which VTERM
                 is run.

Remote terminal - The 'outgoing' port on the local VAX, which is
                  connected to the remote computer, typically by
                  way of a modem.
1 SET

Allows you to set various values
2 BUFFER

Format:  SET BUFFER /REMOTE=nn

nn must be an integer between 1 and 128.  When VTERM initializes, 
this value is set to 4.  In general, a larger value decreases CPU 
utilization by VTERM, while smaller values give a more 
comfortable 'feel' to the user.  With values greater than one, up 
to a second may elapse between when a character is received from 
the remote computer and it appears on the local screen.
2 LOCAL_ECHO

Format:  SET LOCAL_ECHO

This sets VTERM in 'half-duplex' mode, where the input from the 
local terminal is echoed by VTERM as it is sent to the remote 
computer.
2 SPEED

Format:  SET SPEED = speed

Speed may be 110, 300, 1200, 2400, 4800, or 9600.  When VTERM is
initialized, speed is set to the value specified by the logical
name VTERM$SPEED.  If the logical does not exist, or translates
to an invalid value, 1200 baud is used. 
2 LOG

Format:  SET LOG filename

The VTERM log is a generally faithful reproduction of the output
to the local terminal, but may have some small differences.  In
particular, VTERM edits any record that contains a backspace 
character to remove the backspace and the character preceeding it 
from the buffer.
3 Qualifiers

/APPEND

Specifies that the new log should be appended to an existing one.
If no log exists with the name specified, creates a new one.

/CLOSE

Specifies that the current log should be closed.  If a file name
is specified with /CLOSE, the file name is ignored.  /CLOSE should
only be used to speicify the /PRINT qualifier.  No new log file is
opened.

/PRINT

Specifies that the log file should be spooled to the default print
queue when it is closed.

2 NOLOG
Format:  SET NOLOG

Stops logging and closes the log file.
1 STOP
Exits from VTERM.  Control-Z is equivalent to STOP. VTERM.COM
will prompt you for whether or not it should deallocate the port.
If the auto-dial modem was used to make the call, deallocating
the port will terminate the phone connection. 
1 DIAL
How to dial calls with the VADIC 3451 auto-dial modem:

Enter control-E <CR>
    This will invoke a message and "*" prompt.

Enter D<CR>
    Modem will prompt "NUMBER?"

Enter the desired number (dashes and parens are allowed, but 
    ignored). Use the backspace key to make corrections.
  Notes:
    - The number will not be echoed as you enter it.
    Terminate the number with <CR>.   The modem will then
    echo the number.
    - The letter "K" will cause a 5 second pause in the dialing
    sequence.  It is most useful when specified at the end of the
    phone number to extend the number of seconds required for a
    connection to be established.

Hit <CR> to start dialing.
    After a period of time, the modem will respond with either
    "ON LINE" or "FAILED CALL".  ON LINE indicates that the call
    completed, and you are now connected to the target machine.
    FAILED CALL indicates either that the line was busy, did not
    answer, or the call did not complete in a specified time 
    period.  You can not tell why the call did not complete.
1 Initialization

When VTERM is entered, it takes the following steps:

o  Assigns channels to the terminal devices using the
   following logical names:
 
   Name            Device
   ----            ------
   VTERM$REMOTE    Port to remote computer
   SYS$COMMAND     Port on local computer

o  Sets the remote terminal speed to the value specified in
   the logical name VTERM$SPEED (or 1200 baud if the logical
   is invalid)

o  Opens the file VTERM$INIT and executes any vterm commands
   that it contains.

o  Displays the message "VTERM - Ready" on the local terminal.
  
o  Waits for input from either the local or remote terinal.
