Modems and Modem software
=========================

Question:   My modem software doesn't work at 9600 baud with my
            Windows and DOS Software.

Answer:     A OS/2 2.0 VDM (virtual DOS Machine) only provides 1000
            VDM interuppts per second.  This is too slow for 9600
            baud.  Lower the modem speed to 4800 Baud or lower.
            This will be addressed in a future version of OS/2 2.0.

Fax Boards and Fax Software
===========================

Question:   My Windows Fax Software doesn't work from a seamless
            windows session.

Answer:     Some software does not work correctly in a WINOS/2
            window, try running it from a full screen WINOS/2
            session.

Question:   My fax software doesn't work at 9600 baud with my
            Windows and DOS Software.

Answer:     A OS/2 2.0 VDM (virtual DOS Machine) only provides 1000
            interuppts per second.  This is too slow for 9600 baud.
            Lower the fax speed to 4800 Baud or lower.  This will
            be addressed in a future version of OS/2 2.0.  If you
            cannot slow down your fax software, then it will not
            currently work in OS/2 2.0.  APAR# PJ03990.

WINOS/2 Scanners and Scanner Software
====================================

Question:   Logitech Scanman 256 doesn't run on WINOS/2, but runs
            in a VDM by itself.

Answer:     Logitech Scanman uses a DLL which makes a 4B interrupt
            call. This interrupt is not supported under WINOS/2.
            This interrupt is planned to be supported in the next
            release of WINOS/2.  No workaround. APAR#PJ04100-
            closed PER - available next release.

Question:   FOTOTOUCH doesn't run on WIN-OS/2.

Answer:     FOTOTOUCH uses the same DLL Logitech Scanman uses which
            makes a 4B interrupt call.  This interrup is not
            supported under WINOS/2.  It is planned to be supported
            in a future release of WINOS/2.  No workaround.
            APAR#PJ04100 - closed PER - available next release.

Multimedia
==========

Question:   Soundblaster applications do not work correctly under
            WIN-OS/2.

Answer:     Some Soundblaster and Soundblaster PRO applications
            will work OK.  However, many soundblaster applications
            have problems.  Most of these problem applications try
            to use more than 1000 interrupts per second to generate
            sound.  The Parrot program provided with soundblaster
            is one of these problem applications.  Applications
            that use DMA for sound generation instead of the
            interrupt method will have a better chance of running.
            The 1000 interrupt per second problem is being
            addressed.  Currently there are no work arounds if you
            are experiencing problems with a Soundblaster board.
            APAR PJ03959.

Question:   MIDI software and boards do not work correctly.

Answer:     Some MIDI software and applications also experience
            problems because of the 1000 interrupts problem.  No
            workaround at this time.  APAR# PJ04498
