XCON: X.25 Cards Supported Through Direct Hardware Interface |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SUMMARY
Microsoft Exchange Server supports Eicon X.25 cards by communicating
directly with the hardware, rather than communicating with the hardware
through a device driver. This makes it difficult to add support for
additional X.25 cards, because Microsoft Exchange Server must be modified
to support additional cards.
Most other devices are supported by communicating with the hardware through
a device driver, which makes it relatively easy to add support for
additional devices. Support for additional devices is provided by
additional device drivers, which can easily be installed on an existing
Microsoft Exchange Server computer.
MORE INFORMATION
Microsoft recognizes the need for Exchange Server to support additional
X.25 cards. We have modified the Microsoft Exchange Server 5.5 message
transfer agent (MTA) so that X.25 cards are supported by communicating with
the hardware through the Windows sockets API (Winsock). Support for
additional X.25 cards can now be provided by Winsock-compatible device
drivers supplied by the hardware manufacturer.
This feature is included in the latest Microsoft Exchange Server version
5.5 U.S. Service Pack. For information about obtaining the Service Pack,

S E R V P A C K
The Exchange Server documentation states that the Eicon cards are the only
X.25 cards supported by Exchange Server. This is not true; in some cases,
X.25 cards manufactured by Cirel and SAT are also supported. For additional
information about X.25 support for Cirel and SAT cards in Exchange Server,
please see the following articles in the Microsoft Knowledge Base:
