OSBPFAXW - OS/2 WARP BONUS PACK FAXWORK LITE PROBLEMS
01/18/95


================================================================

1.  Why do I get a "FMD<port number> not responding" message
    when using the FaxWorks Lite Application from the OS/2 WARP
    BonusPak?


The problem can be one of several things:


1.  The serial port is not configured correctly for OS/2.

    Before configuring FaxWorks, make sure the modem is working
    with OS/2.

    Review the Performance Considerations reference in the
    Information Folder.

    Review the parameters for the COM.SYS device driver in the
    Command Reference in the Information Folder.  Use the SEARCH
    facility to find the COM.SYS parameters.

    Both the base OS/2 serial communication device driver
    (COM.SYS) and the FaxWorks Lite device driver (FMD.SYS)
    require parameters to describe serial ports COM3 or
    COM4.  Serial ports COM1 and COM2 are configured
    automatically, provided they are set to standard I/O
    addresses and IRQs.  The FMD.SYS device driver and
    the COM.SYS device driver use the identical format.

    The parameters for the COM.SYS and FMD.SYS device drivers
    must match the physical settings of the serial adapter or
    internal modem.  The IRQ and I/O addresses are determined by
    the actual device (i.e.  internal modem) and NOT the OS/2
    device driver.  To determine the I/O addresses and IRQs on an
    ISA bus system, you need to compare the actual device with
    the setting listed the documentation shipped with the
    adapter.

    For example, if an internal modem is present at I/O address
    03e8h, is configured to use IRQ 5 and is the third port
    (COM3), the COM.SYS and FMD.SYS would be configured (in the
    CONFIG.SYS file) as follows:

        DEVICE=C:\OS2\BOOT\COM.SYS (3,03E8, 5)

        DEVICE=C:\FAXWORKS\FMD.SYS L (3,03E8,5)



    The MODE command can be used to verify that the port has been
    configured correctly for OS/2 operation.  The MODE command is
    documented in the Command Reference in the Information
    Folder.  The COM.SYS device driver recognizes a serial device
    is present if the MODE command completes without an error.

    If the MODE command works, you can try the following
    test:  Go to an OS/2 command prompt and type:

        ECHO ATA > COMx:

    where COMx: is the port used for the MODE command. for
    example COM1:.

    This command tells the modem to raise the audible carrier
    signal.  To reset the modem, type:

        ECHO ATZ > COMx:

    If the test works, the modem is configured correctly for
    OS/2.  If it fails, there is probably a a hardware conflict
    or configuration error.


2)  The FaxWorks device driver is not configured for the
    serial port.

    The FaxWorks Device Driver (FMD.SYS) uses the identical
    parameters as the COM.SYS device driver.  The FMD.SYS device
    driver also requires the 'L' parameter.  These parameters are
    documented in the \FAXWORKS\README.DOC file.


3)  The FaxWorks application is not configured correctly.

    The FaxWorks lite README.DOC file is in the \FAXWORKS
    directory.  Review this file for modem settings.

    The CLASS 1 FAX standard works better with
    the FaxWorks Lite application.  If you have problems
    using the CLASS 2 FAX standard and the FAX Modem is capable
    of using the CLASS 2 FAX standard, customers should configure
    FaxWorks to use the CLASS 1 FAX Standard.

    Notice the "USE HW FIFO" setting for the FaxWorks Lite
    application, it should only be checked if the MODE commands
    returns "BUFFER=AUTO".  Below are the recommended settings
    for CLASS 1 FAX Modems:


    BAUD:       9600
    CLASS:      CLASS1
    FEATURES:   CHECK TCF SIGNAL
                RECEIVE EOP DELAY
                USE HW FIFO (if BUFFER=AUTO) ***


    NOTE:       Any valid port address and IRQ should work.  Some
                14.4k Data/FAX modems have problems trying
                to FAX at 14.4k.  Make sure it works at 9600
                before increasing the BAUD rate.

    Note:

    HW FIFO refers to the hardware being compatible with the
    NS16550a UART.  This is determined by using the MODE
    command and looking at the BUFFER setting.  If BUFFER is set
    to N/A, then this is not a NS16550a compatible UART.



4)  The Data/Fax Modem is not supported by the application.

    Only Data/FAX modems that are compatible to the NS16450 /
    NS16550a are supported by the FaxWorks Lite application.
    Serial devices such as Intelligent Digiboards, Hayes ESP
    devices and Intel Satisfaction (internal) modems are not
    supported by the FaxWorks Lite application.  See the
    \FAXWORKS\README.DOC for further information.
