            PREMIUM EXEC DATA FAX\SEND RECEIVE MODEM AND BITFAX SOFTWARE

    PROBLEM:       Unable to receive facsimiles while using BITFAX version
                   3.07.03, by Bit Software Inc., on a Premium Exec with a Data
                   FAX/Send Receive Modem.  May also display error message: "COM2
                   not functional--Try another COM port", if the "Test Fax Modem"
                   option is selected under BFtest.

    CAUSE:         The modem needs to be initialized before connecting the
                   Premium Exec to a facsimile machine.

    AFFECTED
    SYSTEMS:       All Premium Exec systems using the BITFAX software with a Data
                   FAX/Send Receive Modem with one of the following part numbers:

                           230175-002 or 230175-003

    SOLUTION:      Execute the "ASTMODEM ON" file which is included with the Data
                   FAX/Send Receive Modem package before the BITFAX software is
                   executed.  This file can either be executed from the
                   AUTOEXEC.BAT file or from a DOS command prompt.  Use "ASTMODEM
                   OFF" to disable the modem.  The "Internal Adapter" option
                   under SYSTEM SETUP should also be set to "ENABLE".
