Motorola SM56 Quick Start User Manual
If there is a problem making or receiving a call or transmitting data, and your communications
application does not explain the problem, check the following list of symptoms and tips.
•
The modem installs at COM 5 (or higher)
Some ISP applications, such as America on-line, do not communicate with a COM port higher
than COM4. If the SM56 installs on COM5 or higher, force the modem to a lower COM port as
follows.
1. Open the SM56 Control Panel application.
2. Select the Advanced tab.
3. Click on the radio button for the desired COM port. Note that unavailable COM ports are
grayed out and not selectable.
Note: For SM56 ISA modems Build 58 and later include this feature on the Control Panel applet.
If using earlier builds, edit the PortName data in the Windows Registry HKLM-->Enum--
>ISAPNP-->nnnn, where nnnn corresponds to the modem's plug and play ID. Change PortName
data to the desired COM port. The changes take effect as soon as the Registry editor (REGEDIT)
is closed. There is no need to restart the PC.

Windows 95/98 DOS box applications do not work with the modem
1. The SM56 PCI modem does not directly support Windows 95/98 DOS box applications. If you
are using the SM56 PCI modem you must use a third party application that traps and
virtualizes the COM ports. One such application is provided by Pacific Commware, Inc.
(Ashland, Oregon). They can be found on the Web at www.pacificcommware.com. The
application is called TurboCom/95 Pro, and works on Windows 95 and Windows 98
platforms. Note that Motorola have not completely tested and qualified this product for SM56
DOS box support, but have verified basic functionality.
2. If using the SM56 ISA modem, open the Control Panel.
3. Double click the System icon.
4. Expand the Modem branch.
5. Double click the Motorola SM56 modem.
6. Select the Modem tab. Make a note of the COM port number.
7. Select the Resources tab. Make a note of the IRQ number listed.
8. For DOS support to operate correctly, the SM56 modem cannot occupy the standard IRQ for
the COM port number.
