Q V T
A DEC VT220 Emulation Program
For IBM PC Compatible Computers
Version 3.55
October 1989
QVT is a program for IBM PC's and compatibles which fully
emulates the DEC VT series of terminals, including the VT52,
VT100/102, and VT220. In addition to terminal emulation,
QVT also allows the user to perform file transfers using
the Kermit, Xmodem, Ymodem, and Zmodem protocols, and offers
conveniences such as auto-dial and auto-login.
Though it may be used as a general-purpose PC communications
program, QVT excels when used to carry on interactive sessions
with host computers which require the use of DEC terminals,
such as the DEC VAX. In this context, QVT provides high per-
formance, extremely rigorous emulation, and convenient mapping
of the DEC keyboard to the PC keyboard.
QVT will run on all IBM Personal Computers and PS/2's. All IBM
display systems are supported, including EGA, MCGA, and VGA.
Installation
------------
The files included in this package are:
QVT_PC.EXE the QVT executable
QVT.HLP an on-line help file
DEFAULT.VT a model configuration file
We recommend that a directory be created on your hard drive
where these files can be placed. If you wish to use QVT from
anywhere on your hard drive with no loss of convenience, you
should create an environment variable 'VT_DIR', and assign
to it the name of that directory. This 'SET' command should
be included in your AUTOEXEC.BAT file.
User Interface
--------------
The QVT user interface is simple and consistent. All commands
(with two minor exceptions) are accessed through a group of
pull-down menus; the headings of these menus are displayed
in the menu bar across the top of the screen. To invoke a
menu, press the <Alt> key together with the first letter of
the menu. At the left side of the menu bar is the '■' symbol;
this is the 'System' menu, and is invoked with the combination
<Alt-X>.
After a pull-down menu has been invoked, you may select one
of its options by moving the highlight bar to the desired
item, then pressing the <Enter> key. If you wish to erase a
menu without selecting any of its items, press the <Esc> key.
Below is a summary of QVT's commands:
'System' Menu (Invoke with <Alt-X>:
Exit Terminate QVT, break phone connection
Suspend Terminate QVT, preserve phone connection
DOS Run a copy of COMMAND.COM within QVT
Help Get help on a QVT function
'File' Menu (Invoke with <Alt-F>
Kermit Send Transmit files using Kermit
Kermit Receive Receive files using Kermit
Kermit Get Get files from Kermit server
Kermit Finish Terminate a remote Kermit server
Xmodem Send Transmit a file using Xmodem
Xmodem Receive Receive a file using Xmodem
Ymodem Send Transmit files using Ymodem
Ymodem Receive Receive files using Ymodem
Zmodem Send Transmit files using Zmodem
Zmodem Receive Receive files using Zmodem
Text Upload Transmit text data without protocol
Capture Data Save all incoming data on disk
Screen Image Save screen image on disk
'Settings' Menu (Invoke with <Alt-S>
Terminal Modify QVT's keyboard and display parameters
Communications Modify QVT's communications parameters
Phone Numbers Enter/update phone number list
Function Keys Define programmable function keys
General Enter/update miscellaneous parameters
Load Config Load a config file from disk
Save Config Save current settings in a disk file
'Modem' Menu (Invoke with <Alt-M>
Dial Dial the number of the current system
Script Execute the current script file
Hangup Break the modem connection
Number Choose a phone number from a list
The following keyboard commands are also available:
<Alt-H> Invoke 'Help' menu
<Alt-K> Display keyboard map
<Alt-L> Turns the QVT status line on and off
<Alt-P> Turns auto-print mode on and off
Configuring QVT
---------------
To change QVT's operating parameters, perform the following
procedure:
1. Invoke the 'Settings' menu, then select the 'Terminal'
or 'Communications' option.
2. When these options are selected, a new popup window will
be displayed which shows a portion of QVT's current operating
values.
3. To change one of these values, use the arrow keys to move
the cursor to the desired item, then repeatedly press the
<GreyPlus> key to step through the available values.
4. When all displayed values are as you want them, press the
<Esc> key to erase the window, then press <Esc> again to
erase the 'Settings' menu.
The sample config file, DEFAULT.VT, includes comments which
briefly explain all of QVT's configurable parameters.
DEFAULT.VT is a plain ASCII text file, and may be printed or
viewed with any standard text editor or browser.
Modem Configuration
-------------------
QVT is designed to work with Hayes-compatible modems. In order
for QVT's auto-dial feature to work properly, your modem must
be configured such that the CD and DTR indicators are NOT
forced on by the modem. Instead, the CD indicator should be
set to track with the carrier from the remote modem, and the
DTR indicator should be set to respond to the presence of a DTR
signal from the PC.
On the Hayes Smartmodem 1200, these configurations are performed
by setting switches 1 and 6 to the UP position. On the Hayes 2400
modem, the commands 'AT&C1' and 'AT&D2' should be used. If you
are not using a Hayes modem, consult your modem's owner's manual
as to how to achieve this configuration.
You should also make sure that your modem has result codes
enables. The Hayes command to do this is 'ATQ' or 'ATQ0'.
Modem Initialization
--------------------
QVT does NOT automatically place a carriage return at the
end of the modem initialization string. If your modem requires
a carriage return as a command terminator (as do Hayes modems),
you must put one at the end of your initialization string,
using the notation '^M'.
Keyboard Mapping
----------------
This version of QVT is a 'vanilla' implementation for the
101-key 'Enhanced' keyboard. By 'vanilla', we mean that
this version of QVT will work both on machines that have
BIOS support for the 101-key keyboard, and on those that
don't (e.g., many XT clones). It does not attempt to use
the top row of the numeric keypad for 'PF' keys. A version
of QVT that does is available to registered users (see below).
