& Introduction
UNICOM is a data communications application specifically designed
for users of the Microsoft Windows operating environment
(versions 2 and 3).
UNICOM can perform data communication tasks in the background
while other applications are running. You may switch to another
Windows application at any time.
UNICOM Release 1.4 includes the following features:
X/Y/ZMODEM, Kermit, CompuServe B, Quick B and ASCII file
transfer protocols implemented for full background operation.
Color ANSI-BBS, VT52 and TTY Terminal Emulation supporting user
selectable terminal fonts that span OEM and ANSI character
sets.
A 250 Line Terminal Scroll Buffer is provided.
A new Script Language supports more than 35 commands with a
Trace Mode for debugging.
A Script Scheduler allows pre-programmed execution of up to
eight script files each at specific days and times.
Directory assisted batch dialing and redialing is supported
for users with Hayes compatible modems.
An Online Help System allows instant access to general help and
script command topics. The user manual is also available for
direct reference from the online help.
A unique journaling feature lets you record mouse and keyboard
operations for later playback.
Keyboard macros, File logging, File Paste and Print Screen.
UNICOM provides some unique features that support the Windows
environment. You can:
Transfer the contents of a Clipboard from one computer
directly into the Clipboard of another. This provides you
with the ability to transfer many types of Windows-unique data
formats between computers. Some of these formats include:
Excel Spreadsheets (SYLK, DIF), Bitmap Images (from Paint),
Metafile Pictures (from Designer), Text (from Notepad) and any
format that can be placed on the Clipboard.
Operate your computer in a multi-user mode with UNICOM's host
mode. A built-in command processor allows a validated remote
user to examine or transfer files on a designated disk drive.
This operation is transparent to any user who may be at the
keyboard directly operating other Window applications.
Operate multiple program instances. Advanced users with the
appropriate hardware configuration may initiate simultaneous
background file transfers with multiple remote systems.
Send a Screen Snapshot directly to the Clipboard.
& Hardware and Software Requirements
UNICOM requires Microsoft Windows version two or three to be
installed and properly configured on your computer. If your
particular version of UNICOM does not operate properly with
Windows version 3, contact Data Graphics for information on how
to obtain a release of UNICOM designed for that version.
Before installing UNICOM on your computer check the following:
1) If a BUS mouse is installed in your computer, make sure the
mouse interrupt level does not conflict with interrupts reserved
for serial port operation. The BUS mouse interrupt is set via a
jumper on the interface board. Consult your mouse installation
manual.
2) Your serial port(s) (COM1 and COM2) should be set for
interrupt operation using IRQ4 and IRQ3 respectively. The
interrupt levels are typically selected via jumpers located on
your serial interface board or on the motherboard. Consult your
computer reference manual.
3) Microsoft Windows version 2 may contain a BUG in the
communication port driver. If your version of Windows is dated
before April 1989, you should obtain a replacement communication
port driver (named COMM.DRV) from Microsoft and reinstall Windows
using this replacement file.
4) A Hayes compatible modem must be present to support UNICOM's
directory assisted dialing and call hang-up features.
The modem dip switch settings should be set to the manufacturers
DEFAULT positions. The modem must be configured to return
VERBOSE responses.
Also, please note that certain operations such as Clipboard to
Clipboard transfers require enough temporary memory and disk
storage to hold the data being transferred. This storage is
released after the transfer operation is completed.
& Installing UNICOM
The UNICOM 1.4 distribution disk should contain the following
files:
File Description
UNICOM.EXE - The UNICOM executable program.
UCLIB.EXE - UNICOM Runtime Support library.
UNICOM.DIR - A sample dialing directory.
UNICOM.CFG - A default program configuration file.
UNICOM.WRI - The UNICOM Online Manual.
UNICOM.HLP - Online Help Text File.
UCSCRIPT.HLP - Script Online Help Text File.
UC-READ.ME - UNICOM release notes.
CSERVE.SCR - An example UNICOM login script file
To install UNICOM,
1) UNICOM requires that Microsoft Windows 2.x or 3.x be
installed and working on your computer.
If you are upgrading from a previous version of UNICOM, do
not mix your old UNICOM.CFG with that of a new UNICOM release.
UNICOM configuration files are not compatible across releases.
2) Insert the distribution disk in your floppy disk drive.
3) Copy the files to any directory on the destination drive
where you wish to store UNICOM. You will need to remember this
directory path and enter it into the UNICOM file path window
from within the program setup menu.
The support file: UCLIB.EXE must be placed in a directory
listed in your search path as defined by your MS-DOS PATH
environment variable. This PATH environment variable is set in
the MS-DOS AUTOEXEC.BAT file. Consult your DOS operating
manual for more information about the DOS PATH environment
variable.
4) Before running UNICOM, it is a good idea to check the items
listed in the previous Hardware and Software Requirements
section.
5) Activate UNICOM and enter your license number by pressing
the ENTER LICENSE NO. button that appears on an opening start-
up screen. The license number is printed on your receipt and
should be saved for future reference should the program need to
be re-installed. Licensing disables the opening startup
screens and prevents their return during program operation.
Should UNICOM be moved to another computer or modify the
Windows WIN.INI file, it may be necessary to enter the license
number again to disable the built-in nagware screens should
they reappear.
& Running UNICOM
UNICOM may be activated from DOS using the following syntax:
UNICOM [configfile]
By omitting the optional [configfile] parameter, UNICOM will
look for a default configuration file named UNICOM.CFG.
From DOS, type the command (depending upon your windows version):
WIN UNICOM
-or- WIN386 UNICOM
To activate UNICOM from the Microsoft Executive or File System,
doubleclick (using a mouse) on the file: UNICOM.EXE.
When invoked without a configuration file parameter, additional
UNICOM instances will attempt to access a configuration file
named UNICOM2.CFG. If this file cannot be located, the port
settings will default to COM2, 1200, N, 8, 1.
When UNICOM is activated for the first time, a file path setup
window will appear prompting you to enter a UNICOM files,
upload and download directory.
The files directory should be set to the drive and directory
where UNICOM has been installed. The download directory should
be set to the drive and directory where files received from
data transfers are to be stored. The upload directory should
be set to the drive and directory where UNICOM will first look
to locate files for upload selection.
Enter the pathnames into the edit fields within the dialog box.
Paths defined here are valid only for the current UNICOM
session. To make the paths permanent, activate the SAVE SETUP
option from within the SETUP menu. Paths are stored in your
Windows WIN.INI file.
An error message will be displayed if any of the path fields
contain an invalid directory or if UNICOM could not locate its
executable files in the directory specified in the FILES
DIRECTORY field.
At the start of each program run, the configuration file
'UNICOM.CFG' is accessed (from the file path set previously) to
determine what communication port will be used and other
operating parameters. If UNICOM cannot locate this file, the
port will default to COM2, 1200 baud, No Parity, 8 data bits
and 1 stop bit.
Should a communication port fail to open, UNICOM will display a
message box to indicate the failure. The port configuration
dialog window will be displayed automatically. A valid
communication port should be selected.
When a communication port is successfully opened, UNICOM will
try to initialize the Hayes compatible modem if the port was
configured for a modem connection. Should the message "Modem
Not Responding" appear, this means UNICOM could not get the
modem's attention. Make sure the communicatons port and modem
are configured properly. Ensure that the modem is set to
return VERBOSE responses.
& UNICOM and Windows 3.0
This product will be supported for the Windows
version 3 environment when it becomes available.
Should this version of UNICOM fail to operate under
Windows 3.0, contact Data Graphics for information
on how to obtain a Windows 3 specific version.
Registered users may upgrade free of charge.

execution using a new Script Scheduler.
The Modem Init String can now be user-provided or
selected from the modem setup window.
A User Defined Dialing Prefix is supported to support
extended phone numbers for special dialing. Systems
to be dialed using a prefix are identified using an
asterisk in the first column of directory system name.
Directory entries can be dialed with a double mouse click.
The dialing directory will remember your selections.
An Error Report Disable option has been added to disable
reporting of selected communication errors should they
occur.
Windows Control Panel, Notepad, and additional UNICOM
instances can be activated from a menu. There is no
need to leave UNICOM to invoke these utility programs.
& Transferring Files
A powerful feature of UNICOM is the ability to exchange
information between computers. The protocols provided with this
software will allow you to transfer files between many different
computers. UNICOM performs this transfer task in the background,
so you may switch to other running applications.
Downloading Files
To download a file into your computer, start the download
procedure on the remote system and select the DOWNLOAD FILE
option from the Control menu. The PgDn key or the DOWNLOAD
screen button may also be used. UNICOM will then prompt you to
select a protocol from a dialog box. You may choose from XMODEM,
YMODEM, ZMODEM, Kermit, ASCII, CompuServe B and Quick B protocols.
After a selection has been made, UNICOM will prompt you for
a filename in which to store the file. You are not prompted for
this information for ZMODEM, CompuServe B and Kermit transfers
since the name is provided by the remote.
NOTE: The communication port is switched to 8-N-1 automatically
for all transfer protocols (except ASCII). The port is switched
back to the previous settings after the transfer is completed.
Throughout the course of the file transfer, an information
window is displayed so that you may easily monitor the transfer
operation. This window provides the following information: the
name of the file, number of bytes transferred, current block
number, error count and any messages generated from the use of
the selected protocol. A bar graph display has been added to
give you a visual read-out as to the amount of data received
or transmitted.
To abort a transfer in progress, mouse users may select the
ABORT button from the information window. Keyboard users must
press the ESC key.
Uploading Files
To upload a file to the remote system, instruct the remote
computer to receive a file from you. Initiate the file upload on
your computer by selecting UPLOAD FILE from the Transfer menu.
The PgUp key or the UPLOAD screen button may also be used. An
upload file selection window will appear that will allow you to
search your disk for the file to be selected. The file to be
uploaded may be entered by name or selected from the listbox
containing directory entries.
The upload file directory listbox may be set to display
files from a different drive. Just enter the drive letter and
terminating colon (example D:) in the edit box then press return.
The listbox will be directed to display the directory on that
drive.
For ZMODEM file transfers, a Batch Upload File Selection box
will appear containing two listboxes. The listbox on the left
displays the current directory of files from which to select. The
listbox on the right contains the selected files for transfer.
Batch selections are made by double clicking the mouse on a
selected file. Keyboard users must highlight the selection and
use the tab key to activate the ADD button. Once this is done,
the file is added to the right listbox containing selected files.
Use the ADD button from this window to make batch selections.
When you are finished, select GO! to initiate the ZMODEM upload.
& Clipboard Transfers
The contents of the Clipboard may be transferred between two
computers equipped with UNICOM software. Using this feature,
many types of Clipboard formats may be exchanged. Some of these
formats include: Bitmaps, Metafile Pictures, Text, User Defined
Formats, SYLK, TIFF and more...
To send a Clipboard format to a remote UNICOM, the user on each
end must agree to the transfer operation by using the keyboard
to communicate the request. This transfer must be coordinated
by both parties so that both UNICOM's can be commanded at
the same time - one to receive, the other to transmit.
A Clipboard format is transferred as a temporary file
between two UNICOM systems. This requires sufficient temporary
disk and memory space on both computers to hold the format.
& Dialing from the Directory
To use the automatic dialing feature built-in to UNICOM, the
dialing directory must be populated with entries each
containing a name, phone number and communication parameters.
The directory maintenance buttons located on the lower right
corner of the dialing directory allow the directory to be
edited and saved. Once you have created your directory,
UNICOM can establish a phone connection for you.
Just highlight the desired directory entry using the mouse
or keyboard then select the DIAL button. UNICOM will set
the communication parameters and begin dialing.
Hayes compatible modems require that commands be issued
using specific communication settings. If the communication
parameters for the entry being dialed are different from the
table below, the modem may not respond properly when
UNICOM sends a command to dial.
BAUD Word Size Parity Stop Bits
0 - 300 7 or 8 Even 1 or 2
7 or 8 Odd 1 or 2
7 or 8 None 1 or 2
1200 or 7 Even 1 or 2
greater 7 Odd 1 or 2
8 None 1 or 2
& Journaling
Journaling is a feature used to record a UNICOM session for
later playback. Keyboard and mouse interaction with UNICOM
can be recorded and played back exactly as it was recorded.
This can be useful for demonstrating the use of the program
or to completely automate an interaction with a remote computer.
Journaling has some built in Microsoft limitations: Some dialog
windows will only respond to actual input during a journal play-
back.
& Pasting Clipboard Text
Clipboard text may be pasted (transmitted) to the remote
host computer. This operation is equivalent to uploading an
ASCII file.
An ASCII file can be copied to the Clipboard using
a program such as Notepad. The text can then be pasted
(uploaded) to the remote host by selecting PASTE from the Edit
menu.
The ASCII upload settings apply to this operation.
Select the 'ASCII Xfer' menu selection from the Setup menu to
view (or change) the ASCII transfer settings.
& Host Mode Operation
Host mode allows remote password protected access to the
files within all directories on a designated drive. The password
and assigned drive are set by selecting the HOST option from the
Setup menu.
To toggle host mode ON or OFF, select HOST MODE from the
Control Menu. Once enabled, UNICOM monitors the port for a
remote user login.
A remote user MUST TRANSMIT TWO CONSECUTIVE CARRIAGE RETURNS
to cause UNICOM to display the HOST IDENTIFICATION STRING and
prompt the user for a login name. Once a login name is entered,
the user is prompted for a password. Should the password be
accepted, the remote user is granted access and presented with an
option menu. Passwords are case sensitive and should be entered
by the remote user exactly as it appears in your host
configuration screen.
& HELP!: Solving Communication Errors
--------------------------------------------------------------
UNICOM and Error Reporting
--------------------------------------------------------------
UNICOM uses the Microsoft Communication port driver
built into Windows to communicate to the outside world.
Communication errors are detected by the Windows port
driver. UNICOM reports errors in the form of PORT STATE
messages anytime the driver encounters an error.
Unlike many other communication programs, UNICOM is not
in low level control of your hardware. When an error
occurs in communication, it is detected by the driver
then reported by UNICOM.
In other words, to correct communication errors, the
solution must be to the satisfaction of the Microsoft
Port driver built into Windows.
It is through UNICOM by which you instruct how
communication is to be set. If UNICOM complains,
it does so on behalf of the Microsoft driver.
-------------------------------------------------------------
Identifying Communication Errors
-------------------------------------------------------------
The first step in solving a communication difficulty is
to identify the cause. The three most common causes
are listed as follows.
1) A mismatch in port settings may exist between your PC
and the remote system that you are connected to.
Make sure that UNICOM and the remote system are set
to communicate using the same baud rate, parity,
stop bits and wordsize.
2) Your PC hardware may be configured improperly and
thus preventing proper operation of the port.
The hardware settings to be aware of include:
* A BUS Mouse Interrupt Level jumper setting
(located on the bus mouse interface card) should
be set to an interrupt level that does not conflict
with an interrupt reserved for your serial port.
Consult your mouse installation manual.
* Check the interrupt settings for you serial port(s).
COM1 should be set for IRQ4. COM2 should be set for
IRQ3.
Interrupt settings are typically selected via a
jumper on your serial card or motherboard.
Consult your computer reference manual.
3) Your version of Windows may contain a bug in the
communication port driver provided by Microsoft.
A bug exists in Windows 2.0 - 2.1 dated before
April 1989. You should obtain a file called COMM.DRV
(or COMMDR.ARC ) from Microsoft and re-install Windows
using this replacement file. This file should be
available on CompuServe in the MS-APP area in
library 1 or 2.
--------------------------------------------------------------
Solving Communication Errors
--------------------------------------------------------------
Correcting problems is often accomplished through a
process of elimination. If the problem you are having
is cause 1 (above), it cannot be addressed until
causes 2 and 3 are checked and corrected (if necessary).
At this point it is assumed that you have verified your
hardware configuration and have re-installed Windows
using the replacement communication driver.
If the problem still persists, it is very likely a
mismatch in communication settings between your
PC and the remote host computer.
See 'HELP with CompuServe' for troubleshooting
communication difficulties with this service.
Setting Communication Parameters
Setting communication parameters involves determining
the baud, parity, wordsize and the number of stop
bits required for the computer you wish to connect
with. It then becomes a matter of setting your PC
to match the parameters of the remote computer using
UNICOM's Comm Port setup option.
If you are not sure of the communication parameters
required by the remote computer contact the
operator of the system or refer to the following
table.
System Type Typical Settings
-----------------------------------------------
Bulletin Boards 8-N-1
TYMNET 7-E-1
TELENET 7-E-1
CompuServe 7-E-1 (and/or 8-N-1)
Some network services or data links impose
their own communication operating parameters when
connecting your PC with a remote host computer.
If you are sure of the operating parameters
required by the remote host and are still experiencing
difficulty, the data link may be the cause. If this
is the case, an alternate (or more direct) method of
connection may be required.
If you have exhausted all the above possibilities and
just can't solve the problem, feel free to contact
Data Graphics - See 'How to Obtain Additional Help'.
& HELP with CompuServe
PROBLEM:
After dialing into CompuServe, characters appear
'garbled' before and/or after entering my USERID number.
ANSWER:
CompuServe requires that you be aware of 3 communication
settings:
1) The CompuServe access port settings.
The Access port prompts you for the system,
user id and password.
Settings are either 7E1 or 8N1.
2) The CompuServe online TERMINAL settings.
After entering your USERID during login
at your access port, CompuServe will switch
to ONLINE settings. These online settings
can be viewed or changed by typing
GO TERMINAL from the CompuServe prompt.
3) Your PC Communication Port Settings set by
UNICOM using the Comm Port menu selection
from the Setup menu.
Should your PC Communication settings differ
from 1 or 2 above at any time, UNICOM may
report a PORT STATE RX-PARITY message and
characters received can be lost.
When you first call into CompuServe via an access port,
your PC communication settings must match those of the
access port.
There are two types of settings with CompuServe:
8 Data Bits, No Parity and 1 Stop Bit,
or
7 Data Bits, EVEN Parity and 1 Stop Bit
DO THIS:
1) Determine the Parity and Word Size (or Data Bit Size)
settings for the CompuServe access port that you dial
into. You may need to contact customer service at
800-848-8990 for this info.
2) Log into CompuServe and change your TERMINAL SETTINGS
to match the parity and word size of your dial-in
access port. Type GO TERMINAL at the CompuServe
! prompt. Make this setting permanent when asked to
make the change for the session only or permanent
(for all future sessions).
3) Set UNICOM to match the parity and wordsize for
CompuServe in the Dialing Directory using the
Change option.
& HELP!: Directory ADD, CHANGE and EDIT PREFIX buttons
PROBLEM:
The ADD, CHANGE and Edit Prefix buttons in UNICOM's dialing
directory do not activate the directory editor using
Windows 386.
ANSWER
A low memory condition (conventional memory) may (at times)
prevent these edit windows from appearing when activated.
The following steps are recommended:
1) Upgrade to a newer version of Microsoft Windows.
2) After placing the following line in your config.sys,
reboot your computer.
BUFFERS=30
3) Operate UNICOM without executive replacement programs.
(i.e. remove Command Post)
4) If all else fails, contact Data Graphics.
Any one or more of the above steps should be tried to
eliminate the problem.
& NOTE: UNICOM, Windows and COM3
QUESTION
UNICOM provides a COM3 option in the port configuration
Window but I can't access this port - I do have the
hardware. What's wrong?
ANSWER
UNICOM depends upon the capability of the Microsoft
communication port driver built into Windows from which to
communicate with the outside world. Unlike most other
comm programs, UNICOM does not control or talk directly
to your serial I/O ports. All communication is done via
the Microsoft serial port driver provided with Windows.
Windows 2 supports COM1 and COM2 only.
Support for COM3 will be provided in a future version of
Windows.
