Exit/Suspend Program
Both of these commands terminate QVT and return to DOS.
The difference is in their treatment of the communications line. 'Exit'
will break any existing phone connection, whereas 'Suspend' will not.
'Suspend' will also save the QVT screen image to a file in the current
directory; this file will have the same root name as the current config
file. The saved image will be restored to the screen the next time that
config file is used.
The 'Exit' option is for use when you want to exit permanently from QVT.
The 'Suspend' option is intended for occasions when you want to exit
temporarily from QVT and perform some other tasks, and then return to
your QVT session.
end
DOS Shell
Starts up a copy of COMMAND.COM within QVT. This makes it possible to
issue DOS commands to perform file operations, then return to QVT at the
exact point where it was interrupted.
This option is superficially similar to 'Suspend', the difference being
that 'Suspend' actually terminates QVT, whereas 'DOS' merely pushes it
into the background while you execute DOS commands.
You should use 'DOS' when all you need to do outside QVT is a few simple
DOS operations, like displaying a directory listing. If you need to do
more extensive tasks, you should use 'Suspend' instead.
When are finished using DOS, and wish to resume your QVT session, enter
the command 'EXIT' at the DOS prompt.
WARNING! Do not attempt to start another copy of QVT from the DOS shell!

Kermit Uploads
The procedure for transmitting a file using KERMIT is as follows:
1. Start KERMIT on the remote system, normally by issuing the 'KERMIT'
command. For binary file transfers, enter the Kermit command
'set file type binary'.
2. Make sure that the remote Kermit is set to the same parity as QVT.
This is done using the Kermit 'set parity' command.
3. At the 'Kermit>' prompt, issue the command 'receive'.
4. Invoke the QVT 'File' menu, and select the command 'Kermit Send'.
This will bring up the Kermit Upload dialog box.
5. Enter the name of the file to transfer. DOS pathnames and/or
wildcards are acceptable.
endpanel
6. Answer the prompt asking whether Kermit should operate in Text or
Binary mode by entering a 'T' or 'B'; no carriage-return is required.
Your response to this prompt should be consistent with the file type
expected by the remote Kermit.
The transfer will now proceed until completion.
end
Kermit Downloads
The procedure for receiving a file using KERMIT is as follows:
1. Start KERMIT on the remote system, normally by issuing the 'KERMIT'
command. For binary file transfers, enter the Kermit command
'set file type binary'.
2. Make sure that the remote Kermit is set to the same parity as QVT.
This is done using the Kermit 'set parity' command.
3. Issue the 'send' command to the remote Kermit, along with the name of
the file that you intend to transmit. Most Kermit implementations will
accept wildcards.
4. Select 'Kermit Receive' from the QVT 'File' menu. This will bring up
the Kermit Download dialog box.
endpanel
5. The cursor will be positioned in the 'File Name' field. You may now
enter the drive and directory where the incoming files should be
placed. Press <Tab> if you don't want to make an entry.
6. Answer the prompt asking whether to use Kermit's Text Mode or Binary
Mode by entering a 'T' or 'B'; no carriage return is required.
Your response to this prompt should be consistent with the file type
expected by the remote Kermit.
The transfer will now proceed until completion.

X/Y/Zmodem Uploads
Although there is no standard host user interface for these protocols,
they do have in common the principle that the remote side should be
started first.
1. Make sure that the remote computer is ready to accept the file.
On a host minicomputer, this will usually involve starting a program
that is used for file transfer with these protocols; an example of
such a program is Omen Technology's 'rb' program for Unix and VMS
systems.
On PC bulletin boards, you should select the 'Upload' option from
the BBS menu.
2. Select the appropriate 'Send' command from the QVT 'File' menu.
3. Enter the name of the file that you want to transfer.
For XMODEM, only a single file can be transferred. Y and Zmodem,
however, are able to transmit multiple files in a single batch.
endpanel
In the current release, batch transfer is supported only in the
sense that you can include wildcards in the filename, and all files
that match the template will be transferred.
Batch transfer of multiple files with unrelated names will be incor-
porated into a future release of QVT.
In all cases, full DOS pathnames are supported.
4. For Xmodem and Ymodem only:
Answer the prompt which asks whether to use large or small packets.
When uploading to a host minicomputer, small packets should be used.
For PC Bulletin Boards which support Ymodem or Xmodem-1K, you may
use large packets.
5. The transfer will now proceed until completion.

X/Y/Zmodem Downloads
Although there is no standard host user interface for these protocols,
they do have in common the principle that the remote side should be
started first.
1. Make sure that the remote computer is set up and ready to start the
file transfer
On a host minicomputer, this will usually involve starting a program
that is used for file transfer with these protocols; an example of
such a program is Omen Technology's 'sb' program for Unix and VMS
systems.
On PC bulletin boards, you should select the 'Download' option from
the BBS menu.
2. Select the appropriate 'Receive' command from the QVT 'File' menu
endpanel
3. For XMODEM transfers, enter the name that the file will have on the
PC.
For YMODEM or ZMODEM, you may enter the drive and directory where you
want the incoming file(s) to be placed. This is optional, and you can
press <Tab> to skip this step.
4. For XMODEM only:
Answer the prompt which asks whether to use CRC error-checking. The
standard reply is 'N'; however, the CRC method is provides superior
error detection and is therefore preferable where available.
5. The transfer will now proceed until completion.
end
Text File Upload
This command is useful when you have a small text file that you want to
copy directly up to the remote system without protocols. For example, you
may have a file that you want to send to another user on the host system
over the host's mail facility. You can start up the mail utility, put it
into 'input mode', where it is waiting for you to type in the message, then
use QVT's 'Text Upload' command to transfer the PC file directly into the
remote mail system.
Characters will be displayed on the screen as they are echoed by the host.
end
Log File
This command causes the incoming stream of data to be copied verbatim to a
file on the PC. Unlike some other communications programs, QVT writes the
data to disk as it is received, with the result that the amount of data that
you can capture is limited only by the amount of space on your disk.
To use this command, you begin by selecting the 'Log File' command from
the 'File' menu. A window will pop up which contains a field for you to
enter the name of the file that should be opened for logging. As soon as you
hit <Return>, QVT will return you to interactive mode. At this point, all
received characters will be written to the log file as soon as they are
displayed on the screen.
To close the log file, simply select the 'Log File' command again.
end
Capture Screen Image
Use this command to copy an exact image of the screen to a disk file. The
image will be written in the form of 25 lines of 80 characters, with a
carriage-return/linefeed at the end of each line. The resulting file is
suitable for printing, o
