INTERFACE ADDS LINUX SUPPORT TO CLEO 3780PLUS SOFTWARE.

Interface Systems' (Nasdaq: INTF) Cleo Products Group has added support for the Linux operating system within Cleo 3780Plus, its e-Commerce communications software.

Cleo 3780Plus allows Unix, Windows -- and now Linux -- users to exchange data with each other and with mainframe and midrange systems. Linux is an operating system created by a team of volunteers that has recently begun gathering widespread corporate support.

"This upgrade expands our company's reach from the oldest mainframe to the newest operating system," said Donald Redding, vice president of Cleo. "Nothing could better symbolize our support for business-to-business electronic communications."

Cleo 3780Plus is widely used for electronically exchanging order and purchase information with Fortune 500 companies such as Ford, Blue Cross/Blue Shield and Wal-Mart. More than $327 billion is expected to change hands in business-to-business transactions by 2002, according to the Forrester Research Group.

In addition to providing Cleo 3780Plus for more than 15 years to thousands of customers, Cleo also supports 3270 host connectivity through SNA and TCP/IP. Asynchronous communications are supported by Cleo A+, and Internet communications are handled by Cleo LexiCom. This combination of products makes Cleo one of the leading suppliers of business-to-business electronic communications tools.
