                           PRODUCT LINES WITH FAX

                Fax Modem Users Have Desktop, Portable, PC-internal,  
                        Macintosh and Palmtop Options

          SKOKIE, Il. -- March 23, 1992 -- U.S.Robotics today announced 
          the addition of ten new fax/data modems to its Sportster and 
          WorldPort product lines. The first of these products to ship 
          will be the WorldPort Palmtop Fax/Data modem (March) and the 
          Sportster high-speed fax products (April). All of U.S.Robotics' 
          fax/data modems, which include 9600 bps Group III fax and data 
          speeds ranging from 2400 bps to 14,400 bps, will be shown in April 
          during Spring COMDEX, Booth #W2347.

          "Adding fax/data modems to these popular product lines provides 
          a strong one-vendor solution for any customer's data communications 
          needs," said Marshall Toplansky, U.S.Robotics vice president of 
          marketing. "Our new fax/data modem lineup gives U.S. Robotics 
          resellers a product for every customer, including products for home 
          office, entry-level, small business and portable use."

          The new Sportster and WorldPort fax products are designed for ease 
          of use. The included fax software is intuitive and user-friendly, 
          even for complex operations such as sending broadcast, or group 
          faxes, performing background operations, and sending delayed faxes 
          with a specific date and time for transmission. The fax products 
          include these features, plus phone books to store frequently-used 
          phone numbers and fax groups, logs that record both incoming and 
          outgoing faxes, and "quick fax" or "express fax" capabilities for 
          short faxes.

          What sets these fax modems apart from others is that they include 
          U.S.Robotics-designed software, providing complete compatibility 
          and allowing them to function seamlessly as integrated products.  
          With the exception of the Sportster products for the Appler 
          Macintosht, all the new fax products include fax software designed 
          and developed by U.S. Robotics.

          "We've leveraged our hardware and software design expertise to 
          produce hardware and software that functions as one product," added 
          Toplansky. "We've made our easy-to-use data modems into easy-to-use 
          fax/data products."

          Sportster Products
          The first fax products to ship in the Sportster product line, 
          designed for entry-level, home-office and small business customers, 
          will be high-speed fax/data modems. Sportster fax modems, with the 
          exception of the products designed for the Apple Macintosh, will be 
          available in external and internal form factors, and range in price 
          from $229 to $599. The products will include 9600 bps Group III fax 
          capabilities, BLAST FAX software, designed and developed by 
          U.S.Robotics, and a choice of data speeds ranging from 2400 bps to 
          14,400 bps (V.22 bis, V.32 or V.32 bis data transmission).  

          BLAST FAX software makes sending a fax as easy as printing a 
          document. A document is selected with simple commands and sent via 
          BLAST FAX's dialing directory, which allows users to pre-program 
          frequently-used fax numbers.  

          With BLAST FAX, What You See Is What You GetBLAST FAX performs 
          advanced features not found in many fax software packages, including
          attribute retention, which permits users to fax a document and 
          retain such attributes as bold type, italics, etc. Using attribute 
          retention, users have "WYSIWYG" capabilities; the document they see 
          onscreen will look exactly the same when faxed.

          Other important features of BLAST FAX software include: background 
          operation; delayed send capabilities; and group broadcast 
          capabilities. Background operation enables the sending and receiving
          of faxes in the background while working in other applications.  
          Delayed send allows users to prepare documents in advance, 
          specifying a time and date for transmission. This feature reduces 
          fax costs by allowing the user to send faxes when phone line 
          costs are lower. Group broadcast capabilities allow the sending of 
          multiple faxes simultaneously, each with an automatically-generated 
          custom cover sheet.  

          Sportster high-speed fax modem products will ship in April; 
          Sportster 2400 bps medium-speed fax modem products will ship in May. 

          Macintosh Products
          U.S. Robotics' fax/data products designed for the Apple Macintosh 
          include Macintosh-compatible FAXSTFt software from STF Technologies, 
          Inc. The Sportster 14,400 Mac&Fax has 9600 bps Group III fax 
          capability with a 14,400 bps CCITT V.32 bis data channel, and is 
          scheduled to ship in April. The Sportster 2400 Mac&Fax has 9600 bps 
          Group III fax capability with a 2400 bps data channel, and will 
          ship in May. The bundled FAXSTF software includes features such as 
          background operations, delayed send and group broadcast. The modems 
          are priced at $599 and $329, respectively. 

          WorldPort Products
          The WorldPort portable product line currently includes eight 
          products, three of which have fax capabilities. The WorldPort 
          products, widely known as the most complete portable modems, 
          include features such as dual phone jacks, LEDs, speakers and an 
          acoustic interface.  

          The WorldPort brand, which includes the world's first portable V.32 
          modem, now scores another coup with the fully-featured WorldPort 
          9696, the first portable modem to combine V.32/9600 bps data 
          capability with send-and-receive Group III fax capability and MNP 
          2-5 error control and data compression. The WorldPort 9696 features 
          9600 bps CCITT V.32 data transmission, and with MNP 5, has a maximum 
          effective throughput of 19,200 bps. It includes WorldPort Fax 
          Software, and will ship May 31 for a list price of $699.

          All WorldPort fax/data modems with WorldPort Fax Software include 
          delayed send capabilities, allowing users to prepare documents in 
          advance, specifying a time and date for transmission. WorldPort fax 
          modem users can also send and receive faxes in the background while 
          working in other applications, and can send group faxes, which 
          allow the sending of multiple faxes simultaneously.

          WorldPort Palmtop: Only Palmtop Modem With ASCII Fax Capability
          In addition, the WorldPort line will include the new WorldPort 
          Palmtop Fax/Data modem, a 9600 bps send-fax modem with 2400 bps 
          data communications capabilities. Designed specifically for palmtop 
          or hand-held computers, such as the Hewlett-Packard 95LX and the 
          Sharp Wizard, the WorldPort Palmtop is the only palmtop modem in the
          world capable of sending ASCII text as a fax without using fax 
          software. 

          The product bypasses the need for software by automatically 
          converting ASCII text into fax format for transmission. Its ability 
          to fax documents without fax software saves the palmtop's valuable 
          memory space for other applications. The WorldPort Palmtop Fax/Data 
          modem will ship in March, at a suggested list price of $249.

          U.S.Robotics Fax Modems Provide Cost Savings
          Computer-based fax has several advantages over stand-alone fax 
          machines, including cost-savings and increased time-efficiency.  
          According to the International Computer Facsimile Association, it 
          takes approximately 10 minutes to send a conventional document via 
          fax (time includes printing a document, retrieving it from the 
          printer, walking to the fax machine, feeding the document, and 
          waiting for transmission to be completed).  In contrast, sending a 
          document via computer-based fax takes approximately one minute -- 
          or one-tenth of the time.  

          "Fax has complete acceptance in the business world," added 
          U.S.Robotics' Toplansky. "Everyone takes advantage of the 
          simplicity and convenience of faxing. Now U.S.Robotics modems 
          provide the added convenience of an easy-to-use, fully-functional 
          fax machine and a high- or medium-speed modem integrated in one 
          piece of hardware." 

          Higher Image Quality Via Computer-Based Fax
          Conventional fax machines scan documents, the primary cause of image 
          distortion. Images sent via fax modem bypass the scanning process 
          and are significantly clearer than traditionally-faxed documents.
