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.
APAR# PJ03990.
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
