      | Announcing Special Versions of PortInfo and IRQInfo for OEM and |
      |                        Software Providers                       |
      +-----------------------------------------------------------------+

     Two special versions of PortInfo are now available for use with your
     organizations products and services:

        PortInfo for Customer Support - Provides a specially modified
           version of PortInfo designed specifically for Customer Support
           use. PortInfo-CS removes the end user interactions and creates a
           comprehensive report about the Modems and Com Ports that can be
           faxed, emailed or read to your customer support representatives.

        Modem Finder for DOS - Provides your communication software
           accurate information about the Modems (speed, command set, 
           manufacturer and port used) and Com Ports (port address, IRQ,
           and Windows setup) on any computer.

     Also, a special version of IRQInfo is available to provide detailed
     information about the IRQs in use and available in the computer. This
     precise utility can be used to create very reliable hardware
     installation programs.

     CTS, Inc. will be happy to provide a quote on providing a complete
     custom installation program designed to your specifications for any
     hardware or software product.

                 | PortInfo for Customer Support (PortInfo-CS) |
                 +---------------------------------------------+

     PortInfo-CS is a slightly modified version of PortInfo that improves
     on-site and remote customer support. PortInfo-CS runs without entry of
     any "command line" parameters and requires no user interaction to
     perform the complete serial port conflict and modem test. PortInfo-CS
     automatically creates the standard PORTINFO.LOG file that can be
     printed, faxed, emailed or read to you over the phone.

     The standard PortInfo product is modified as follows to create
     "PortInfo-CS":

         * The Program Title will indicate that this is a version licensed
           to your organization:

         * PortInfo-CS will have only three commands: "PortInfo", "PortInfo
           /P" and "PortInfo /?"

         * The command "PortInfo" will cause PortInfo-CS to perform a
           complete conflict and modem test on all ports without user
           interaction. A PORTINFO.LOG file will be created, and all modem
           tests will be performed.

         * Two different modes of operation are available:

           1) No user interaction ("press any key to continue" ) is
           required. This is desirable when capturing the output to a file
           for transmission to your location; or

           2) The user must "press any key" to move to the next screen. This
           is often the best approach when using PortInfo-CS for telephone
           support.

           One mode is selected by you as the default operation. The other
           mode will be activated if PortInfo-CS is run with the "/P"
           command.

         * The command "PortInfo /?" will display an information screen
           which contains licensing and contact information for your
           organization and an "about CTS Inc." message.

     Three optional add-ons are also available:

         * The "Windows Check" module allows PortInfo-CS to compare the
           actual serial ports in the computer system with the BIOS table
           and the Windows SYSTEM.INI file to verify that all port addresses
           and IRQs are set correctly for Windows operation.

         * The "Modem Response" module will capture the modem identification
           responses (ATIn commands) to the PORTINFO.LOG file. This
           includes modem speeds, command set(s) supported and the modem
           manufacturer (when supported).

         * The AUTOEXEC.BAT and CONFIG.SYS files can be included within the
           PORTINFO.LOG file for transmission to your location.

     Availability & Customization Time
     ---------------------------------
     PortInfo-CS is available now. Delivery time from date of order is a
     maximum of 10 business days for standard versions and options.

             | Overview of Modem Finder for DOS   (MFDos.EXE) |
             +------------------------------------------------+
                
     "Modem Finder for DOS" (MFDos) is a "licensed for distribution"
     software tool that identifies which serial (Com) ports on computer
     are used by modems available to DOS applications. MFDos runs as a
     self-contained program that is executed (shelled to) by your
     application or run from a batch file prior to running your
     application.
     
     MFDos creates a binary data file that contains the following
     information for each modem or serial port in the computer:
     
         # of bytes in this record
         Port address 
         IRQ used 
         UART type
         Device
         Port "quality check"
         Data modem speed
         Command set type(s) used for error control commands
         Modem or chip manufacturer (if available)
     
     MFDos creates no screen or user readable output of any kind.

                              +-------------------+
                              | IRQInfo Installer |
                              +-------------------+

     IRQInfo Installer creates a simple comma-delimited file that indicates
     the used and available IRQs (Interrupt ReQuest lines) in any computer.
     IRQInfo does this by actually using the devices already installed in
     the computer - and it *NEVER* reports a "default" or "standard" IRQ as
     other similar utilities do.

     IRQInfo Installer can be run from the DOS prompt, a batch file or
     shelled to by any DOS application to identify the serial ports and
     modems. Your application can process the data file created by PortInfo
     Installer to automatically configure itself for the computer it is
     being installed on.

     Availability
     ------------
     "IRQInfo Installer" will be available in late 1995.
