// Unicom 4.0 - 32 bit Release Notes
// Windows 95 Version

////////////////////////////////////////////////////////////
& If your modem is not listed in the modem setup
Try selecting a similar modem or model from the list.
If you have a string for your modem from another source,
try adding it into the manual modem setup under "User
Entered Init String" then select the User Entered
radio button. If none of the above suggestions work for
you, select the "NOT LISTED" option and contact us for
an updated modems.dat file.
At this point you may wish to construct your own string
using your modem reference manual. Unicom requires
the following: Hardware Handshaking (CTS/RTS),
Carrier Detect (CD) follows line state, Modem set to
Fixed DTE.
& Unicom 16550 FIFO Indicator and Windows 95
Support for the 16550 chip is provided by your
serial port driver which is external to this program.
Unicom can neither detect or control the 16550.
The Unicom FIFO indicator will light if you
have configured Windows 95 properly to use this
device whether the device exists or not.
To configure the 16550, access the system icon
from the Windows 95 control panel. Access the
desired com port and select the Advanced option.
A window will appear to let you enable the
16550 and set the RX and TX trigger levels.
& Fax Implementation Notes
Fax support provided in this release is specific
to CLASS 1 and CLASS 2 fax modems only. The
less popular CAS standard is not supported in
this release. Most fax modems are Class 1 or 2.
Class 2.0 is more recent that Class 2. Since
we could not find a Class 2.0 modem before
releasing Unicom 4.0, no compatibility is implied.
Please contact Data Graphics for information regarding
support for Class 2.0 modems.
Unicom supports GROUP 3, one-dimensional fax
encoding according to the TIA T.4 specification.
Both Hi and Low resolution modes are supported
and are set automatically.
The optional higher fax speeds: 14.4k and 12k are not
supported when using Class 1 in this release.
The network fax support is limited to forwarding
received faxes as Email using MAPI compatible
networks to one or more destinations.
This product has been tested on various fax modems based
on ROCKWELL and SIERRA fax class 1 and 2 chip sets.
& Solutions to Faxing Problems
QUESTION:
How can I tell what Class of fax support is
provided by my modem?
ANSWER:
From Unicom's modem setup window, select
the TEST button. Unicom will report the capability
and select the corresponding capability option for you.
QUESTION:
The fax aborts during transmission or reception.
What is wrong?
ANSWER:
Check the handshake option in Unicom's Comm Port
Setup Window. Try using the hardware or none
options. Also, make sure that a screen saver is
not engaging and that disk intensive applications
are not being used during fax operations. Also, make
sure that your port is set to 19200, 8-N-1. Higher
baud rate settings may cause loss of data.
If the above solution does not work, and you are using
a class 2 fax modem, add the following initialization
to your modem setup string: +FDCC=1,3
Also check that your computer does not have an IRQ
conflict.
QUESTION:
Faxes sent with Unicom appear squished with no vertical
spacing.
ANSWER:
You need to obtain an updated Universal Printer Driver file
from Microsoft named UNIDRV.DLL. It should replace the file
of the same name located in your Windows\System directory.
QUESTION:
Received faxes appear partially or fully scrambled with
no apparent form. What's wrong?
ANSWER:
Some fax modems like FRECOM reverse the bit order
of the image. To correct this problem, place the
following line in the UNICOM.INI file located in the
Windows directory:
[UNICOM]
FAXBYTEORDER=1
QUESTION:
I can't re-transmit a fax file that I received as a
fax. What's wrong?
ANSWER:
If the fax was received with ERRORS, these errors are
being re-transmitted and the fax send may fail.
Errors in the fax will show up as image distortion when
viewing the fax. If all your received faxes have some
clutter on the top of the page, you may need to add
the entry in your Unicom.ini as described in the
previous question.
& Solutions to File Transfer Problems
QUESTION: What is causing many errors during file transfers?
ANSWER:
If you see frequent CRC errors and are getting
unacceptable performance, check to make sure
that HARDWARE HANDSHAKING is being used. This
is set in Unicom's Comm Port setup window.
Your modem may also require an initialization
string to enable hardware handshaking.
If this doesn't correct the problem, an IRQ
conflict may exist with your modem port.
A noisy phone line can also cause this problem.
ALSO, make sure your modem is being configured
with a correct string to turn on HARDWARE HANDSHAKING.
& Call Director Notes
The Call Director feature is designed to take advantage
of Adaptive Answer capable fax modems. Some fax modems
like the USR Sportster cannot distinguish between an
incoming fax or data call.
If your fax modem is not capable of adaptive answer,
the Call Director must be set for FAX ONLY or DATA ONLY
operation. If you are not sure if your fax modem is
capable, clear any Adaptive Answer String entry in the
Call Director Setup window. Unicom will then try to
activate the feature using a +FAA or +FAE command when
the Call Director feature is activated.
Incoming calls directed to certain destinations may cause
Unicom to enter a wait mode thus preventing subsequent calls
from being answered. After a call is answered and directed
for processing, only until control is returned to the Call
Director can subsequent incoming calls be answered.
Please note the following:
DATA
Host Mode - Control is returned to the Call Director
immediately after a remote user logs out.
Terminal - Control is returned to Call Director upon
loss of a data carrier detect signal.
Script - Control is returned when the script terminates.
Other Pgm - Unicom enters a wait mode. Control returns to
Call Director when the external program
terminates execution (closes).
FAX
Unicom Fax - Unicom returns control after the fax is received.
Other Pgm - Same as Other Pgm above
** Some fax modems must be set to fax mode for adaptive answer to
work. Unicom, by default, will set the modem to data mode.
To change this, add the following to the Adaptive answer init
string in the Call Director Setup: +FCLASS=2 (for class 2) -or
+FCLASS=1 (for class 1)
& Unicom 4.0/32 bit and Windows 95
This version is designed for Windows 95. It is a true
32-bit application. Therefore, it will not run on Windows 3.x.
A 16 bit version is available for Windows 3.x.
