Resolved Issues
---------------
The following known issues have been resolved with this release:
-This release contains a resolution for TCP/IP problems that occur
when the same network is accessed via a LAN connection and then
subsequently via a remote dial-up connection in Windows 95/98.
Typically, when the computer is connected to the network via the
LAN, routing tables are constructed that direct packets intended
for the network to the LAN interface. If the computer is then used
remotely and an attempt is made to connect to the same network via
dial-up networking, these packets may not be routed to the dial-up
interface, because the presence of the active LAN interface
results in the system's continuing to route packets to it instead.
In such instances, the simplest solution is to remove the LAN
interface from the computer. However, in the case of a multi-
function adapter, this solution cannot be used.
The drivers included with this release now support a new
configuration keyword named "DynamicLinkDetect" to overcome this
difficulty. The value of this keyword (ON or OFF) can be set by
going to Control Panel/Network/Network of Xircom.../Properties
/Advanced. The default value is ON. The activity governed by this
keyword operates as follows:
ON - The ethernet interface is always active once the adapter is
initialized by the driver. An ethernet cable need not be
connected to the port at boot time for the network side of
the adapter to initialize. If the cable is plugged in
later, or unplugged and then re-connected, the adapter will
dynamically detect the presence of the link and connect to
the LAN. This is the setting recommended unless the
symptoms described above are encountered.
OFF - The ethernet interface will only be initialized by the
driver if an active connection to the network is present at
boot time. If the presence of an active link is not
detected, the ethernet portion of the card will shut down.
As a result the OS will "assume" that the interface is not
present, and no packets will be routed to it. As a result,
the IP routing trouble discussed previously should be
eliminated.
-Hot swapping of the REM56G or CEM56 is now supported when using
SystemSoft Cardworks version 4.x for Windows NT 4.0.
V.90 configuration and use information - S109 register
------------------------------------------------------
Current released firmware for Xircom 56K modem products now
includes support for the v.90 56K modem standard. This firmware
is designed to initially attempt to make a v.90 connection, and
then fall back to K56flex if the host being dialed does not
support v.90. However, the host being dialed must support v.90
autodetect in order for a v.90 connection to be initiated by
default. At this point in time, many v.90 hosts do not yet support
autodetect. In such cases, it will be necessary to issue an
ATS109=2 command to the modem in order to force a v.90 connection.
Please note that if this command is used and a v.90 connection is
not achieved, the modem will fall back directly to v.34. When
S109=2, fall back from v.90 to K56Flex is disabled. To set this
value back to the default, issue an ATS109=1 command.
In summary, the values of this register and the resultant behavior
are:
S109=1 (default) - Negotiates initially at v.90 if host supports
v.90 autodetect. If host does not support
v.90 autodetect or does not support v.90 at
all, will negotiate back to K56flex.
S109=2 - Forces v.90 for PCM connects. If host does not
support v.90, falls directly back to v.34.
Changing the value of the S109 register can be implemented via the
following means:
-When using a terminal emulator program, enter ATS109=n (where n
is the value desired).
-To implement with Windows 95/98/NT dial up networking, go to
Control Panel\Modems. Highlight the Xircom modem and click
Properties. Click Connection\Advanced. Enter S109=n (where n is
the value desired) in the Extra Settings box.
Known Limitations
-----------------
-In order to achieve 56Kbps connects (v.90 or K56flex), there can
be only one digital to analog conversion between the connecting
modems. Also, the modems at both ends of the call must be 56K
compatible to achieve 56K speeds; otherwise a standard V.34
connection (maximum 33.6Kpbs) will be negotiated. Current FCC
regulations limit download speeds of the modem to 53Kbps.
-Full-duplex Ethernet transmission is only supported on 10Mbps
networks. This feature is only available when the Adapter is
connected to switched full-duplex 10Mbps Ethernet hubs.
-In order to connect to a 100Base-TX Ethernet network, Category
5 unshielded twisted pair (UTP) network cable terminating in a
male RJ-45 connector must be connected to a 100Mbps hub or
switch. Check with your LAN Administrator if you are not certain
of your network speed and infrastructure.
-Under OEM Service Release Version 2 of Win95 (OSR2), the multi-
function parent device may be displayed under the Modem category
in addition to the modem device. The modem device string is:
"Modem of Xircom 10-100+56". The other device listed
represents the parent multifunction device.
-When using QmodemPro in DOS with XCEMODI.COM in SHAREIRQ mode,
modem performance will be slow. Xircom recommends using MODE
IO to improve performance.
-Using Windows NT 4.0 with Microsoft Service Pack 1 may cause
some portable PCs to lock up on Shutdown or Restart. Updating
to Microsoft Service Pack 3 resolves this issue.
-If you experience intermittent times where the modem will not
respond to an AT Command while running CMENABLE.COM on a
portable that uses the TI1130 PCMCIA Controller, run XCEMTEST
and choose the test function to determine the IRQ the card is
using and run CMENABLE COMIRQ=x where x is the IRQ determined
by XCEMTEST. See the User's Guide for additional information
on using XCEMTEST.
-The COM Port Monitor Utility (XCOMMON) must be launched prior
to any communication applications in order for it to function.
-In Windows 95 or Windows 98, the REM56G or CEM56 is configured to
install the modem at I/O address 02E8 on COM4 by default. In
some computers, other hardware or virtual ports are already
installed that are using these resources in some manner, and
the presence of these devices will cause the modem to install
on COM5. Some applications may not be able to access the modem
in such cases. In order to correct this and move the modem to a
conventional COM port location (COM1 through COM4), try the
following:
Solution 1
If your computer contains an Infra-red serial port or a standard
serial port that is not being used, disable this device in both
the computer's system BIOS and in Windows via the Device Manager.
Then reboot the computer. In many cases, Windows will then re-
assign the modem to the resources that are now open (typically
I/O address 02F8, COM2) and the situation will be corrected.
Solution 2
If you are unable to disable such devices or Windows fails to
re-assign the port used, try the following:
1. Go to the Device Manager. Locate the "Multifunction Parent"
device entry for the REM56G or CEM56 (this may be located in
either the Modems group or the Multifunction Adapters group).
Double click this entry.
2. Click the Resources tab. Uncheck the box labeled "Use
Automatic Settings".
3. Note the Basic Configuration number the adapter is assigned
to (in most cases this will be 0000). Choose a different Basic
Configuration number to assign the modem to the port desired
according to the following scheme:
Basic Configuration 0005 - I/O address 03E8, COM3
Basic Configuration 0006 - I/O address 02F8, COM2
Basic Configuration 0007 - I/O address 03F8, COM1
We have found the first choice (0005, 03E8, COM3) to be the
best selection in most instances.
4. Once the new configuration is selected, click OK. A warning
message will be displayed indicating you have made manual
changes and asking if you wish to continue. Click Yes. After a
few seconds, the modem will be assigned to the new settings and
the problem should be corrected.
-On some computers running Windows NT 4.0, if NT networking
functionality has not already been installed, lockup and/or
"blue screen" symptoms may be encountered when installing the
REM56G or CEM56 adapter along with networking. This has been
observed primarily on computers that support CardBus. The
following workarounds for this situation have been found to
be successful:
Solution 1
Perform the installation of Windows NT networking WITHOUT the
REM56G or CEM56 adapter in the computer. Assign resources that
are appropriate for your computer. Once the installation process
has completed, shut down the computer and insert the REM56G or
CEM56 adapter in the computer and then reboot.
Solution 2
When initially installing networking, choose the "MS Loopback
Adapter" from the adapter list instead of installing the REM56G
or CEM56 at this time. Once networking is installed, reboot the
computer, remove the "MS Loopback Adapter" from the
configuration, and install the REM56G or CEM56 according to the
instructions in your User's Guide.
Solution 3
In some cases, it is necessary to install the REM56G or CEM56
while installing networking for the purposes of joining a
Domain. This is true in the case of an unattended installation
to an NT domain server. In such cases, download the latest
version of PCMCIA.SYS (pcmfix-i.exe). At the time of this
publication this file can be obtained at the following URL:
ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/nt40/
hotfixes-postSP3/pcm-fix/
Rename the existing PCMCIA.SYS located in the \I386 directory.
Copy the updated version to the \I386 directory. See the
On-Line Help file for additional information.
In a case in which Windows NT has already been installed but
networking has not and the need exists to join a domain in
this manner, overwrite the PCMCIA.SYS file that currently
exists in the \%systemroot%\system32\drivers directory with
the new one. You should then be able to install the REM56G or
CEM56 while installing networking without difficulty.
-With CEM56, the following devices are known to have
performance issues at 100Mbps when using the RJ45 connector
with the CEM56-100BC cable (CABLE-MOD212):
-NETWORTH - SERIES 1000 100BASE-TX CLASS II REPEATER
-COMPAQ - NETELLIGENT 1108 100BASE-T CLASS II REPEATER
-ASANTE - PLUG-AND-PLAY 100TX HUB /12
-BAY NETWORKS - BAY STACK 100BASE-T (without CE Mark,
version with CE Mark works fine)
-PCMCIA adapters may feel hot to the touch after prolonged
periods of normal use in some environments. This is normal and
is not known to affect operation of the Xircom card, the host
computer, or any other peripheral device. However, to avoid
discomfort, use caution when removing the card from your
computer after extended use (see your computer manual for
removal procedures).
