ΓòÉΓòÉΓòÉ 2. INDUSTRY STANDARD (AT BUS) ARCHITECTURE OVERVIEW ΓòÉΓòÉΓòÉ

The original Industry Standard Architecture (ISA) machine (the IBM PC-AT)
allowed for the  definition of up to four serial communications ports.
However, there has never been any hardware architectural standard that defined
the I/O port addresses or Interrupt Request (IRQ) lines associated with serial
ports #3 or #4.  Over the years a convention was established which places the
port addresses for COM3 and COM4 at 03E8 and 02E8 respectively.  This is a
generally accepted convention and is not a standard.

If multiple hardware adapters of any kind (not just communications) are using
the same I/O address, then the effect on your computer will be totally
unpredictable.

OS/2 2.x is an interrupt driven operating system and requires unique I/O
addresses and Interrupt Request lines (IRQs) for each adapter in the system on
an ISA computer system.  ISA systems have what are called "edge triggered"
interrupts in contrast to Micro Channel (MCA) and EISA which use "level
sensitive" interrupts.  Edge triggered interrupts can only be sensed for a very
short period of time.  If a second interrupt arrives from another adapter while
the first interrupt is still being  processed, then the second interrupt will
be lost.  Also, if two  adapters are sharing the same PHYSICAL IRQ then the
processor does not know which adapter (and therefore which OS/2 session) should
get the Interrupt Request (IRQ). In a single tasking  operating system such as
DOS, the sharing of interrupts is not a  problem as only one application is in
use at a time.  OS/2,  however, presents a different set of problems.  If we
have two,  three, or four serial communications adapters, the probability is
now pretty high that we might try to use two or more of them at the same time.
If some of them have previously been set up using shared interrupts, then the
stage is set for mysterious things to happen that probably didn't happen under
DOS.


ΓòÉΓòÉΓòÉ 2.1. ISA BUS ARCHITECTURE ΓòÉΓòÉΓòÉ

On an ISA machine there are a total of 15 IRQ levels available.  These
interrupts are determined by the two INTEL 8259a (or compatible) Programmable
Interrupt Controllers (PIC).  Each PIC is capable of handling 8 Interrupt
ReQuest lines (IRQ) but IRQ2 of the first pic is cascaded (or linked) to IRQ9
of the second PIC.  Any adapter which is physically configured (or "jumpered")
to IRQ2 will recognized by OS/2 as IRQ9.  This is defined by the hardware and
not the OS/2 operating system.  The standard settings, in order of priority,
follow:

Note:  On the IBM-AT (ISA bus) the IRQ9 pin is identical with the IRQ2 pin on
       the original IBM-PC.  If you have an older, 8-bit adapter whose
       documentation states that it uses IRQ2, then be aware that this will
       actually be seen as IRQ9 when plugged into the 16-bit ISA bus.

OS/2 can detect that an interrupt line is shared and will disallow the
simultaneous use.  Assume that COM1 and COM3 were sharing IRQ4 (a fairly common
real situation).  If we tried to use both COM ports at the same time, OS/2
would refuse to allow the second one to start.  A well-written OS/2
communications program would see and report the error from OS/2 that the port
could not be opened.  A DOS application, however, will likely be unprepared to
respond to this strange situation, and may simply hang, waiting for the port
that will never open.

To avoid these problems, make sure that all of your hardware adapters have
their own unique I/O addresses and IRQ assignments.  Unfortunately, on an ISA
machine, OS/2 has no way to query the computer to find out what these settings
are.  Therefore, after checking and setting the adapters according to the
instruction manuals, you must also tell OS/2 what you've done by placing
explicit information into the CONFIG.SYS file.


ΓòÉΓòÉΓòÉ 2.2. ISA, OS/2 AND PARALLEL PORTS ΓòÉΓòÉΓòÉ

The printer port addresses and IRQ levels are hard coded in OS/2 as follows:

Unlike the COM ports, where the addresses and the interrupts can be specified
by parameters to the COM.SYS in the CONFIG.SYS file, the printer port addresses
and IRQs shown above are fixed.  OS/2 assigns LPT1 to the highest printer port
address being used.  The printer address is specified in the printer adapter
board.  With OS/2 you can not use both addresses 3BC and 378 as printer port
addresses.  Both parallel ports (LPTs) would be sharing IRQ7.  Unlike DOS, OS/2
uses interrupts for printing.  The interrupt is triggered by the signal line,
ACK, from the printer.  If the IRQs are not configured correctly or if the
printer cable is missing the ACK line, the printer may work under DOS and have
problems under OS/2.


ΓòÉΓòÉΓòÉ 2.3. ISA AND OS/2 SUMMARY: ΓòÉΓòÉΓòÉ

Even though there is some flexibility for printer and COM port assignments, try
to stick to the standard assignment as shown in the IRQ table above.

The I/O addresses and IRQs are determined by the HARDWARE.  The parameters
passed to COM.SYS do NOT change the hardware; these parameters are a reflection
of the physical hardware settings.

Available interrupts, in order of priority, are: IRQ9, IRQ10, IRQ11, IRQ12,
IRQ15, IRQ3 (if not used for COM2), and IRQ5 (if not used for LPT2).

Physical addresses and interrupts can be indicated in OS/2 to the communication
drivers.  Usual default settings follow:

o COM1 - 03f8 - IRQ 4 (OS/2 & industry default)
o COM2 - 02F8 - IRQ 3 (OS/2 & industry default)
o COM3 - 03E8 - (industry practice)
o COM4 - 02E8 - (industry practice)

There is no OS/2 default setting for COM3 and COM4.  It  must be specified by
the device=x:\OS2\COM.SYS statement (where x: is the installed drive) in the
config.sys file.

An example of address and interrupt assignments follows:

o COM1 - 03F8,IRQ4
o COM2 - 02F8,IRQ3
o COM3 - 03E8,IRQ5   (IRQ5 not being used by LPT2)
o COM4 - 02E8,IRQ10  (would require a 16 bit adapter)
o LPT1 - 378,IRQ7

If interrupt devices are occasionally losing data, try moving to a higher
priority unused interrupt.


ΓòÉΓòÉΓòÉ 2.4. NOTES ON MICROCHANNEL ARCHITECTURE MACHINES ΓòÉΓòÉΓòÉ

OS/2 2.x requires no extra configuration for Microchannel Architecture (MCA)
computers.  MCA computers have the ability to share interrupts although for
best performance, you should try to limit the number of devices sharing IRQ4
and IRQ3 which are used for COM1, COM2 and COM3.  On a MCA machine, COM1 is
defined as IRQ4, I/O address 3f8, COM2 is defined as IRQ3, I/O address 2f8,
COM3 is defined as IRQ3, I/O address 3220 and COM4 is defined as IRQ3, I/O
address 3228.


ΓòÉΓòÉΓòÉ 3. OS/2 2.x COMMUNICATION DRIVERS ΓòÉΓòÉΓòÉ

There have been many enhancements to the serial communication drivers in OS/2
2.x.  These enhancements have been made based on testing and customer feedback.
With the introduction of OS/2 2.1 and any later Service Pack (CSD), there are
three major versions of the serial communication drivers available: OS/2 2.0,
OS/2 2.0 + SP (XR06055) and OS/2 2.1.  The OS/2 2.1 drivers cannot be used with
OS/2 2.0 and system level XR06055.

The major differences between the various drivers are the DOS Settings
available, the command line parameters to the COM.SYS driver and performance

ΓòÉΓòÉΓòÉ 3.1. OS/2 2.0 GA (XR02000) DRIVER PARAMETERS ΓòÉΓòÉΓòÉ

These settings are for those customers who are at SYSLEVEL XR02000 and have ISA
machines and wish to use COM3, COM4, or non- standard I/O addresses must modify
the config.sys file to include the following parameters for the COM.SYS driver.

                  DEVICE=C:\OS2\COM.SYS (n,a,i) [(n,a,i)] . . .


where the last parameter is optional

n = the Com port

a = COM port I/O address (e.g. 03E8, 02E8)

i = IRQ level

For example, to specify that COM3 is at address 03E8 on IRQ5 and that COM4 is
at address 02E8 on IRQ10, use the following statement (assuming that OS/2 is
installed on the C: drive):

                   DEVICE=C:\OS2\COM.SYS (3,3E8,5) (4,2E8,10)

Note that this syntax is actually quite general.  Non-standard parameters for
COM1 and COM2 are set the same way.

The I/O address and IRQ level should be noted in the documentation that came
with the adapter.  Either or both might be fixed values or adjustable to a
range of values via jumpers or switches.  In some cases, you may find that the
values are fixed or that the range of settings available to you is insufficient
to avoid the sharing conflict.


ΓòÉΓòÉΓòÉ 3.1.1. OS/2 2.O (XR02000) DOS SETTINGS ΓòÉΓòÉΓòÉ

The following DOS Settings are available at OS/2 2.0 (XR02000) level of Code:

o COM_HOLD


ΓòÉΓòÉΓòÉ 3.2. OS/2 2.0 SERVICE PACK (XR06055) DRIVERS ΓòÉΓòÉΓòÉ

Those customers who have ISA machines and wish to use COM3, COM4 or non-
standard I/O addresses must modify the config.sys file to include the following
parameters for the COM.SYS driver.  You may also wish to use the new parameter
for spurious interrupts on MCA or ISA machines.  You will have to specify each
COM port with it's IRQ and I/O address.

            DEVICE=C:\OS2\COM.SYS (n,xxxx,ii,s) [(n,xxxx,ii,s)] . . .

where the last parameter is optional.

n  COM port number (usually 3 and 4 but it is possible to configure 1 or 2 to a
   different IRQ or I/O address.

xxxx  COM port address

ii  IRQ level

s  Spurious interrupt handling switch.  Values:

D or d  to remove the COM driver if more than 1000 consecutive spurious
        interrupts occur.  (DEFAULT)

I or i  to ignore spurious interrupts.

Note:  Some UART chips or malfunctioning modems can create interrupts when no
       interrupt is expected.  These interrupts are known as spurious
       interrupts.


ΓòÉΓòÉΓòÉ 3.2.1. SERVICE PACK (XR06055) DOS SETTINGS ΓòÉΓòÉΓòÉ

The following DOS Settings are available at Service Pack (XR06055) level of

ΓòÉΓòÉΓòÉ 3.3. OS/2 2.1 (XR02010) AND OS/2 2.0 SP/2 ΓòÉΓòÉΓòÉ

(XR09999)

The OS/2 2.1 (XR02010) serial device drivers are installed exactly like the
OS/2 2.0 Service Pack (XR06055) drivers. See (OS/2 2.0 SERVICE PACK (XR06055)

(XR09999) level of Code:

o COM_DIRECT_ACCESS
o COM_HOLD
o COM_RECEIVE_BUFFER_FLUSH
o COM_SELECT


ΓòÉΓòÉΓòÉ 3.4. DOS SETTING DESCRIPTIONS ΓòÉΓòÉΓòÉ

The follow sections describe the various DOS Settings which can be set by the
user.  Please refer to the appropriate section for the system level of OS/2 you
are executing to see which DOS settings apply.


ΓòÉΓòÉΓòÉ 3.4.1. COM_DIRECT_ACCESS DOS property ΓòÉΓòÉΓòÉ

When COM_DIRECT_ACCESS is ON, VCOM.SYS will allow a DOS application to access
the communication ports directly.  This DOS property makes LapLink III,
FastLynx, FSDUAT, AS/400 Asynch Router, and MS WORD work in a VDM session.
However, since the buffers in COM.SYS cannot be used, characters may be lost
and some applications may suffer from the lack of buffering.  With most DOS
applications, COM_DIRECT_ACCESS should be set to OFF as the default setting.


ΓòÉΓòÉΓòÉ 3.4.2. COM_HOLD DOS Property ΓòÉΓòÉΓòÉ

The COM_HOLD Dos Property is used to keep a serial port open until the Virtual
Dos Machine (VDM) Session is terminated.  This setting is used for DOS
applications which open the serial port and then spawn another application
which expects the serial port to be opened.  The disadvantage of using this
setting is that even if the DOS application closes the serial port, OS/2 will
keep the serial port open and will not allow any other session to access that
serial port until the VDM session terminates


ΓòÉΓòÉΓòÉ 3.4.3. COM_RECEIVE_BUFFER_FLUSH DOS Property ΓòÉΓòÉΓòÉ

There are four options for this DOS Setting: NONE (default), RECEIVE DATA
INTERRUPT ENABLED, SWITCH TO FOREGROUND and ALL.  The purpose of this option is
to provide more flexibility for configuring DOS applications.  Some DOS
applications are timing sensitive and will not always read every character from
the UART.  Some applications may have delays built in knowing that the data in
the UART will be overwritten in a set period of time.  Since the timing of the
VDM does not match exactly to native DOS, this type of application will not run
correctly under OS/2.  The DOS Settings are described in the following
sections.


ΓòÉΓòÉΓòÉ 3.4.3.1. NONE SETTING ΓòÉΓòÉΓòÉ

When the "NONE" Property is set, no data will be flushed from the receive
buffer (of the OS/2 communication driver).  This is the default action.


ΓòÉΓòÉΓòÉ 3.4.3.2. RECEIVE DATA INTERRUPT ENABLED SETTING ΓòÉΓòÉΓòÉ

When the "RECEIVE DATA INTERRUPT ENABLED" Property is set, any data in the
received data buffer for this DOS session will be discarded whenever the DOS
program enables the received data interrupt.  This option is for DOS programs
which require data to be discarded while the received data interrupt is
disabled.


ΓòÉΓòÉΓòÉ 3.4.3.3. SWITCH TO FOREGROUND SETTING ΓòÉΓòÉΓòÉ

When the "SWITCH TO FOREGROUND" Property is set, any data in the received data
buffer for this DOS session will be discarded whenever the DOS program is
brought to the foreground (from a background state).  Background processes do
not receive as high a priority as foreground processes.  Some DOS applications
which are timing sensitive cannot process the data (which may have accumulated
in the received buffer) if the data is bunched up.  This feature was added for
CAD application using a digitizing tablet.  If there was a great amount of puck
activity while the application was in the background, the application would
occasionally hang when brought to the foreground.  This option corrected the
problem by flushing the accumulated data and allowing the application to start
fresh in the foreground.


ΓòÉΓòÉΓòÉ 3.4.3.4. ALL SETTING ΓòÉΓòÉΓòÉ

When the "ALL" Property is set, both the "RECEIVE DATA INTERRUPT ENABLED" and
the "SWITCH TO FOREGROUND" options are enabled.


ΓòÉΓòÉΓòÉ 3.4.4. COM_SELECT DOS Property ΓòÉΓòÉΓòÉ

COM_SELECT allows the DOS session to select only one communication port to be
used by the session.  The communication ports which are not selected will be
hidden from the DOS session.  There are some DOS applications which take over
every available communication port.  This DOS property is effective in
preventing those DOS applications from taking over all the communication ports.
An example of a DOS application which attempts to control all the communication
ports is LapLink Pro.  If LapLink Pro and another application which accesses a
communication port are executed at the same time, it is necessary to set
COM_SELECT.  The default setting is ALL.


ΓòÉΓòÉΓòÉ 3.5. OS/2 2.0 COMMUNICATION DRIVER DIFFERENCES ΓòÉΓòÉΓòÉ

The major differences between the GA release of the OS/2 2.0 communication
device drivers and the later release of the communication device drivers are:

 1. The parameters which are passed to the COM.SYS device driver.

 2. The enhanced DOS Settings which provide more flexibility in running DOS
    programs.

 3. There have been various defects corrected.  These are noted in a later
    section.


ΓòÉΓòÉΓòÉ 4. OS/2 2.x COMMUNICATION TROUBLE SHOOTING ΓòÉΓòÉΓòÉ

This section will give some insight into trouble shooting communication
problems with OS/2 2.0.  Past experience shown that most problems will be
resolved by one or more of the solutions listed below.


ΓòÉΓòÉΓòÉ 4.1. BOOT TIME ERRORS ΓòÉΓòÉΓòÉ

This section will describe what action to take should the COM.SYS or VCOM.SYS
give an error message at OS/2 initialization (or boot) time.


ΓòÉΓòÉΓòÉ 4.1.1. PS/2 (MICROCHANNEL ARCHITECTURE) COMPUTERS ΓòÉΓòÉΓòÉ

 1. If the COM.SYS driver issues a warning at boot time on a PS/2 or other MCA
    class computer, reboot the computer using the reference diskette and check
    that the port has been properly configured.

 2. If have the PROTECTONLY flag in the CONFIG.SYS file set to YES and you are
    at System level XR06055 or previous, you will need to get the next CSD
    level or OS/2 2.1.


ΓòÉΓòÉΓòÉ 4.1.2. INDUSTRY STANDARD ARCHITECTURE (ISA) COMPUTERS ΓòÉΓòÉΓòÉ

 1. Verify that all IRQ levels and I/O addresses are unique for every adapter.
    The usual problem is that communication adapters (internal modems, FAXes,
    etc) use COM3 and IRQ4 which is already in use by COM1.  You must
    PHYSICALLY change the IRQ on the adapter to one which is not in use. You
    need to refer to the documentation which came with the adapter. (See ISA
    BUS ARCHITECTURE).

 2. Verify that you are passing the correct parameters to the COM.SYS driver in
    the CONFIG.SYS file.  Some PCM machines need to have all the serial ports
    (i.e COM1, COM2) defined to COM.SYS in the CONFIG.SYS.  If you are using a
    serial mouse, do not specify the communication port of the mouse. (See
    COMMON ISA AND MCA SITUATIONS).

 3. There were problems at System Level XR02000 with recognizing some serial
    adapters.  This has been resolved at System Level XR06055 or higher.

 4. If error message during boot: COM PORT not installed because interrupt
    already in use, check for an IRQ conflict with other device drivers or
    hardware.

 5. If the MODE command fails, check the CMOS data area to verify that the I/O
    address is listed.  The OS2/DOS utility, DEBUG, will show the I/O addresses
    listed at location 40:0. (See DETERMINING I/O ADDRESSES FOR ISA COMPUTERS)


ΓòÉΓòÉΓòÉ 4.1.3. COMMON ISA AND MCA SITUATIONS ΓòÉΓòÉΓòÉ

 1. If using LAN SERVER with the UPS monitoring option and having problems at
    boot with COM.SYS or VMOUSE.SYS, move the OS2UPS.SYS driver to before the
    POINTDD.SYS statement in the CONFIG.SYS file.

 2. If system (AT bus or MCA) boots without error but a COM port is still not
    working at all, issue a MODE command (from an OS/2 command prompt) to the
    problem COM port (i.e.  MODE COM1:).  If it indicates that the COM port is
    not installed, check for IRQ conflicts. (See ISA BUS ARCHITECTURE).

    Note:  If the mouse is on a COM port, the MODE command will report a
           SYS1620, the COM port specified is not installed, since the mouse
           has taken that COM port.

 3. You must also check to see that there is a port available to install.  For
    instance, if there is only one serial port and a serial mouse is installed,
    then the COM.SYS will issue a SYS1208 error indicating that there are no
    available ports.  In this instance you should remark (REM) the COM.SYS and
    VCOM.SYS statements in the CONFIG.SYS file.


ΓòÉΓòÉΓòÉ 4.2. APPLICATION DOES NOT RECOGNIZE THE SERIAL PORT ΓòÉΓòÉΓòÉ

This section will describe what to do if an application cannot recognize a
serial port.  If you had errors at boot time, please refer to BOOT TIME ERRORS


ΓòÉΓòÉΓòÉ 4.2.1. OS/2 (PROTECT MODE) APPLICATIONS ΓòÉΓòÉΓòÉ

If the application cannot access the serial port, issue a MODE command against
the serial port in question.  If the MODE command works, contact the vendor of
the OS/2 application.


ΓòÉΓòÉΓòÉ 4.2.2. DOS (REAL MODE) APPLICATIONS ΓòÉΓòÉΓòÉ

 1. If the application cannot access the serial port, try setting (for the VDM
    session) the DOS Setting COM_DIRECT_ACCESS to ON. You have to close the VDM
    session before making changes to the DOS Settings.

 2. Any application which uses QBASIC or BASIC CTTY will need to have the
    DOS_DEVICE DOS setting set to: c:\os2\mdos\comdd.sys.  If OS/2 is not
    installed on C:, then substitute the appropriate drive letter.

 3. See MISCELLANEOUS ERRORS


ΓòÉΓòÉΓòÉ 4.2.3. MISCELLANEOUS ISSUES COMMON TO OS/2 AND DOS ΓòÉΓòÉΓòÉ

 1. Verify that the application is configured for the correct IRQ and I/O
    Address.  Remember that the I/O address for COM3 and COM4 on MCA computers
    is different than ISA computers. (See NOTES ON MICROCHANNEL ARCHITECTURE
    MACHINES)

 2. Issue a MODE command against the serial port in question.  If the MODE
    command indicates that the port is not installed, verify the IRQ and I/O
    address of the serial port.  You should also check to see that parameters
    passed to COM.SYS match the physical configuration of the serial port.

 3. If the modem is external to the computer, try to copy the config.sys file
    to the COM port to which the external modem is attached.  You should be
    able to observe the various indicator lights turning on or flashing.  If
    there is no change in the state of these lights, the external modem may be
    connected to the wrong port, the port may not be at the correct I/O address
    or IRQ level or the port may be broken.

 4. You can use the ECHO command to send modem commands to a modem.  This is
    useful to see if the modem will go "off hook" and get a dial tone.  You
    open up an OS/2 window or full screen session and enter the following:

       ECHO ATDT > COMx:

    Where COMx:is COM1:, COM2: or the COM port you are using. You should hear
    the telephone dial tone.


ΓòÉΓòÉΓòÉ 4.3. OS/2 SYSTEM ERRORS ΓòÉΓòÉΓòÉ

This section will describe various OS/2 generated errors and give a brief
description of what these errors indicate.


ΓòÉΓòÉΓòÉ 4.3.1. TRAPS ΓòÉΓòÉΓòÉ

o If the OS/2 operating system traps when opening a DOS or WIN-OS2 session,
  verify that you have the correct COM.SYS / VCOM.SYS drivers installed.  These
  drivers are a matched set and cannot be mixed between releases.  The OS/2 2.1
  and later service pack drivers are not designed to work on system levels
  XR02000 and XR06055.

o You should also verify any parameters you have giving to the COM.SYS device
  driver (in the CONFIG.SYS file).  On some ISA machines, the device driver may
  have problems if incorrect IRQ and I/O addresses are given.


ΓòÉΓòÉΓòÉ 4.3.2. SYS3175 AND SYS3176 ΓòÉΓòÉΓòÉ

o If the application is an OS/2 application, contact the vendor of the
  application.

o If the application is a DOS application, look at the Stack Segment and
  Extended Stack Pointer (SS:ESP) value in the register dump.  If the ESP is
  very low (or close to zero), the application has run out of stack space.  The
  same logic applies to the Base Pointer (BP) register.  This usually happens
  to applications which have Interrupt Service Routines (ISRs) that are subject
  to time constraints.  The delivery (timing) of interrupts to the VDM session
  is different than under native DOS.  This is a result of tasking (or CPU
  sharing) abilities of OS/2.  Under DOS, the interrupts generated by the UART
  (of the serial port) are delivered in "real" time.  Under OS/2, the
  interrupts are delivered at "task" time which is the time allocated by the
  system scheduler. Since the COM.SYS/ VCOM.SYS device drivers can accumulate
  interrupts, the delivery of the interrupts can be faster under OS/2 than
  under native DOS.  If an application expects to have a consistent delay
  between interrupts, the application may overwrite it's allocated stack due to
  excessive recursion into the ISR.


ΓòÉΓòÉΓòÉ 4.3.3. SYS0099 AND  SYS1798 ΓòÉΓòÉΓòÉ

o OS/2 will only permit one application or session to access a serial port.
  Should an application attempt to access a serial port which is in use, this
  message will appear.  Many DOS applications (such as Personal Information
  Managers) open the serial ports for automatic phone dialing.  You can use the
  COM_SELECT DOS setting to "hide" the serial port from the offending
  application.

o Some DOS applications will open ALL of the COM ports.  Use the COM_SELECT Dos
  Setting in all of the DOS communication sessions (VDMs).

o Most DOS applications are designed to run on a single task system (DOS).
  Even though OS/2 allows multiple DOS applications to execute simultaneously,
  OS/2 is not able to manage file and device sharing for these applications.  A
  well written application would only open a device (such as a serial port)
  when the device is required.  Unfortunately, many DOS applications open the
  device as part of the initialization sequence for the application.  This
  leads to device contention under OS/2.


ΓòÉΓòÉΓòÉ 4.3.4. MISCELLANEOUS ERRORS ΓòÉΓòÉΓòÉ

o If you get "out of memory errors", SYS3175 or SYS3176 errors when opening a
  VDM or WIN-OS2 session, verify any parameters you have giving to the COM.SYS
  device driver (in the CONFIG.SYS file).  On some ISA machines, the device
  driver may have problems if incorrect IRQ and I/O addresses are given.

o There is a situation where a VDM will either not start or COM4: is not
  recognized;  This occurs when COM1, COM2 and COM4 are defined (i.e. no COM3).
  The procedure to correct this error is to define COM4 as COM3 to the COM.SYS
  serial communication driver.  COM.SYS looks at the parameters passed to see
  what LOGICAL NAME (i.e. COM3) is assigned to a particular I/O address and IRQ
  combination.  Even though the serial adapter (i.e. modem) appears to be COM4,
  in reality, all the adapter cares about is the I/O address and IRQ.  An
  example of how to correct the above situation:

       DEVICE=x:\OS2\COM.SYS (3,2E8,5)

  Where "3" is the logical name given to the adapter (i.e. COM3), "2e8" is the
  physical address of the adapter (which is usually for COM4) and "5" is the
  physical IRQ of the Adapter.

  Note:  This problem only occurs at system level XR02000 and XR06055.  OS/2
         will now behave identical to DOS in the way the serial ports are
         identified.


ΓòÉΓòÉΓòÉ 4.4. PERFORMANCE ISSUES ΓòÉΓòÉΓòÉ

There are a few settings you can set to improve the performance of serial
communication applications.  Some of these settings will affect overall OS/2
system performance.  By favoring one type of application (i.e. serial
communications), you may adversely affect other applications in the system.
While OS/2 is an efficient, multitasking operating system, current technology
specifies one CPU which can execute only one machine instruction at a given
time.


ΓòÉΓòÉΓòÉ 4.4.1. OS/2 PERFORMANCE ISSUES ΓòÉΓòÉΓòÉ

OS/2 applications have the ability to be multithreaded, use shared memory and
can designate the priority to be processed at.  Should you be having
performance problems with an OS/2 application, contact the vendor of the
application.


ΓòÉΓòÉΓòÉ 4.4.2. DOS PERFORMANCE ISSUES ΓòÉΓòÉΓòÉ

If the application is a DOS communication program, set the DOS_SETTINGS to the
following:

ΓòÉΓòÉΓòÉ 4.4.2.1. DOS BASED FAX APPLICATIONS ΓòÉΓòÉΓòÉ

There are no DOS based fax applications which are known to work reliably under
OS/2 2.x.  There have been some success with CLASS 1 fax software on a high
powered 486 processor platform.  There has also been some success using the
Intel Satisfaxtion 400 internal modem.  If sending and receiving faxes is an
integral part of the system, an OS/2 fax application (such as FAXPM, FaxWorks/2
and BitFax/2) should be considered.


ΓòÉΓòÉΓòÉ 4.4.3. GENERAL PERFORMANCE ISSUES ΓòÉΓòÉΓòÉ

o Try reducing the IDLE_SENSITIVITY DOS Settings for other DOS applications.
  Some DOS applications continually poll the keyboard which can reduce the
  number of available interrupts at a given time.

o Try increasing/decreasing CACHE to reduce disk activity.  Decreasing DISK
  CACHING may reduce swapping.  You must experiment on your machine.

o Use the Lazy Write (/LW) option on the IFS, CACHE or DISKCACHE option in the
  CONFIG.SYS.

o In the config.sys file, set:

   - PRIORITY_DISK_IO:  NO

   - MAXWAIT:       1

o OS/2 2.0 is a multi-tasking/processing operating system. Slower
  microprocessors (i.e. 386/16mhz) are not going to have enough cycles to
  support communications above 9600 BAUD.

o Even on faster machines there may be problems with supporting high speed
  communications.  Some internal modems have been known to induce spurious
  interrupts which take away from the total number of interrupts that can be
  processed.  Much depends on the quality of the hardware and the ability of
  the software to work with advanced communication processors such as the
  16550AFN UART.


ΓòÉΓòÉΓòÉ 4.5. ISA INTERRUPT REQUEST LEVELS AND I/O ADDRESSES ΓòÉΓòÉΓòÉ

The Industry Standard Architecture (ISA) computers use EDGE triggered
interrupts (versus LEVEL triggered interrupts used in Microchannel Architecture
(MCA) computers).  OS/2 2.x only supports interrupt sharing on MCA computers.
The reason that interrupt sharing is not supported on ISA computers is
performance.  Every adapter in an ISA computer must have a unique IRQ which is
PHYSICALLY defined by hardware jumpers or logically defined by software
supplied by the vendor of the adapter.  The adapter and not OS/2 determines the
IRQ settings.  The same can be said for I/O addresses.


ΓòÉΓòÉΓòÉ 4.5.1. DETERMINING IRQS FOR ISA COMPUTERS ΓòÉΓòÉΓòÉ

On an ISA computer, the only reliable way to verify the IRQ settings for every
adapter is to manually inventory each adapter.  You usually do not have to
worry about the parallel ports, the disk drives or the Math Coprocessor (if one
is installed).  There are some utilities available for DOS which may be able to
indicate if you have an IRQ conflict.


ΓòÉΓòÉΓòÉ 4.5.2. DETERMINING I/O ADDRESSES FOR ISA COMPUTERS ΓòÉΓòÉΓòÉ

There is a technique available for determining which Input/Output (I/O)
addresses are in use by the serial communication adapters which are identified
by COMx.  For other types of adapters, you will have to manually inventory each
adapter.  You usually do not have to worry about the parallel ports, the disk
drives or the Math Coprocessor if one is installed.  The technique to determine
which I/O addresses are in use is detailed below:

 1. Start a DOS Full Screen Session (command prompt).

 2. Enter DEBUG and press the enter key.

 3. At the '-' prompt, enter D 40:0 and press the enter key.

 4. You will see 0040:0000 followed by pairs of hexadecimal numbers.  These
    numbers are the I/O addresses recognized by COM.SYS.  Below is an example
    of COM1 and COM2:

   0040:0000  F8 03 F8 02 00 00 00 00-BC 34....

   This represents 03f8 (COM1) and 02f8 (COM2).  If COM3 was present, it would
   follow COM2's address.

   Note:  If the above procedure shows "E8 02" in COM3's address position,
   there is NOT a serial communication adapter defined as COM3 and there is a
   serial communication adapter defined as COM4, see  MISCELLANEOUS ERRORS

 5. Enter Q and press the enter key to leave DEBUG.


ΓòÉΓòÉΓòÉ 4.6. MISCELLANEOUS ISSUES ΓòÉΓòÉΓòÉ

There may be later OS/2 2.x communication drivers.  These drivers are usually
classed as BETA and are supported through a mail in / FAX feedback form.
Should a beta driver be released, the driver will be available from the IBM
OS/2 Bulletin Board Service or on CompuServ Information Service.  (Call
1-800-547-1283 for information about registering for and accessing the IBM OS/2
BBS, or call 1-800-237-5511 for the OS/2 Support Line.)


ΓòÉΓòÉΓòÉ 5. APPLICATION SPECIFIC PROBLEMS ΓòÉΓòÉΓòÉ

This section will highlight known problems with various applications.  Many of
these applications are listed in the OS/2 README file.


ΓòÉΓòÉΓòÉ 5.1. GENERAL PROBLEMS ΓòÉΓòÉΓòÉ

o If an application hangs, first check that the entire system has not hung. You
  can do this by using the CTRL-ESC sequence which should give you a window
  list.  Sometimes this can take up to one minute if an application is hung.
  OS/2 will then prompt you to terminate the hung application.

o If the CTRL-ESC sequence works, terminate (close) application from the window
  list and then issue a MODE command from the command line.  If the MODE
  command is successful, then there may be a problem with the application.  If
  the application is an OS/2 application, you will need to contact the vendor
  of the application.  If the application is a DOS application, experiment with
  some of the DOS Settings especially the COM_DIRECT_ACCESS property.

o Another thing to check when serial communication applications hang is the
  status of the port.  Use the MODE command to turn off XON, IDSR, ODSR and
  OCTS.

o If an application is experiencing a lot of data loss, you can lower the baud
  rate, upgrade to the latest release of OS/2 or change the settings in the
  CONFIG.SYS file (See GENERAL PERFORMANCE ISSUES).  You can also try setting
  OCTS=ON and RTS=HS using the MODE command.  If the application is an OS/2
  application, contact the vendor of the application.

o If a DOS application is not able to "auto answer" a modem, try the
  COM_DIRECT_ACCESS DOS Setting.


ΓòÉΓòÉΓòÉ 5.2. SPECIFIC APPLICATIONS ΓòÉΓòÉΓòÉ

This section will detail known problems about specific applications and will
offer suggestions to correct the situation.


ΓòÉΓòÉΓòÉ 5.2.1. AUTOCAD 12.0 WITH A DIGITIZING TABLET ΓòÉΓòÉΓòÉ

AutoCad 12.0 will now see a digitizing tablet.  This feature was added at
System Level XR09999 and OS/2 2.1.  There are some restrictions:

o The application appears to be very sensitive to the timing of the interrupt
  delivery.  The application will only work on a 486/33mhz processor or better.

o You need to set the COM_RECEIVE_BUFFER_FLUSH DOS Setting to
  SWITCH_TO_FOREGROUND.


ΓòÉΓòÉΓòÉ 5.2.2. Compuserv Information Manager (CIM) (Dos Version) ΓòÉΓòÉΓòÉ

CIM will only work under OS/2 2.1 and System Level XR09999if IRQ2 (IRQ9) must
be used.  Otherwise the application should work on standard IRQ/IO Address.


ΓòÉΓòÉΓòÉ 5.2.3. CrossTalk for Windows ΓòÉΓòÉΓòÉ

Use the MODE command to set BUFFER=OFF.


ΓòÉΓòÉΓòÉ 5.2.4. DOW JONES LINK ΓòÉΓòÉΓòÉ

This application requires the COMDD.SYS device driver.  (DOS (REAL MODE)
APPLICATIONS)


ΓòÉΓòÉΓòÉ 5.2.5. FAXWORKS/2 (PMFAX) ΓòÉΓòÉΓòÉ

o There was a problem with OS/2 disabling the serial port when using
  FAXWORKS/2.  The Softnet BBS service has a private fix for OS/2 2.0.  The
  problem has been resolved at System Level XR09999. The problem may also
  appear on PS/2 (MCA class) machines in OS/2 2.1.  The Softnet BBS will be
  provided a fix when available.

o This application will work with the INTEL SatisFAXion fax modems under OS/2
  2.x.  Please contact Softnet for further information.

o FAXWORKS/2 requires a parameter passed to the FMD.SYS file to be able to
  share IRQ's on a MCA class machine.  The statement should look like:

   - DEVICE=x:\PMFAX\FMD.SYS -S

     Note:  The "S" MUST BE upper case!

o If using an IBM Internal 2400/9600 fax/modem, you need to get 1.30b of
  FAXWORKS/2.


ΓòÉΓòÉΓòÉ 5.2.6. FT TERM 2.1 ΓòÉΓòÉΓòÉ

FT Terminal (version 2.1) would not dial out correctly on some machines.  This
problem was not reproducible at System Level XR06055 or higher system levels of
OS/2 2.x


ΓòÉΓòÉΓòÉ 5.2.7. GOLDEN COMPASS FOR OS/2 ΓòÉΓòÉΓòÉ

There have been performance problems reported against Golden Compass for OS/2
especially if a Virtual Dos Machine (VDM) is opened while Golden Compass is
connected to CompuServ.  The developer of the application is aware of the
problems and can be contacted via CompuServ (GO OS2AVEND and enter section #2).


ΓòÉΓòÉΓòÉ 5.2.8. INTEL SatisFAXion 400 Internal ΓòÉΓòÉΓòÉ

There has been some success with the Intel Satisfaxtion 400i fax/modem.
Previous versions of this modem have not worked reliably with the INTEL
supplied software.  FAXWORKS for OS/2, however, does provide support for most
of the Intel Satisfaxtion 400 modems.  Please contact Softnet for further
information.

See Also  INTEL SATISFAXTION 400 (internal) FAX/Modem


ΓòÉΓòÉΓòÉ 5.2.9. LapLink III, Laplink PRO ΓòÉΓòÉΓòÉ

If you are at system level XR02000, remark out VCOM.SYS otherwise  use the
COM_DIRECT_ACCESS DOS Setting.  You must also use the MODE command to set IDSR,
ODSR and OCTS of all the COM ports to OFF unless you use the COM_SELECT DOS
Setting


ΓòÉΓòÉΓòÉ 5.2.10. MAXIMUS/2 ΓòÉΓòÉΓòÉ

You must use the MODE command to set OCTS=ON to keep Maximus/2 from overflowing
the modem with data.


ΓòÉΓòÉΓòÉ 5.2.11. Mirror III ΓòÉΓòÉΓòÉ

This application is similar to CrossTalk.  Use the MODE command to set the
BUFFER=OFF.


ΓòÉΓòÉΓòÉ 5.2.12. OS/2 DATABASE APPLET ΓòÉΓòÉΓòÉ

The OS/2 Database Applet requires that the user customize the dialing and the
hangup strings.  Below is an example of each which works with 100% Hayes
compatible modems:


 DIALING STRING       AT&F&D3L0DT

 HANGUP STRING        ATH0Z


ΓòÉΓòÉΓòÉ 5.2.13. PC/ANYWHERE's AWSEND ΓòÉΓòÉΓòÉ

PC Anywhere and other similar applications try to get back to a DOS command
which is not possible when the application is specified in the PATH and FILE
NAME of the ICON.  There is a simple test to see if the following fix will
work.

 1. Make a copy of the application object (icon).

 2. Using the copy of the object, click with the right hand Mouse button and
    select the settings menu option.  Replace the PATH and FILE NAME with a
    '*'. This is identical to the DOS FULL SCREEN object (icon).

 3. Click on the copy of the object to start it.  You should be at a DOS
    command prompt.  Enter the name of the application and test the failing
    portion.

   If the application works, then substitute the following for the PATH and
   FILE NAME:

   x:\OS2\MDOS\COMMAND.COM

   Where 'x' is the OS/2 drive letter.

Substitute the following for PARAMETERS:

 4. /p /k  x:\path\file.exe

 5. Where x:\path\file.exe is your application.


ΓòÉΓòÉΓòÉ 5.2.14. PCBOARD ΓòÉΓòÉΓòÉ

PCBOARD requires COM_HOLD=ON with system level XR02000 release but requires
COM_HOLD=OFF with XR06055 release.


ΓòÉΓòÉΓòÉ 5.2.15. PM TERMINAL (OS/2 APPLET) ΓòÉΓòÉΓòÉ

There have been changes to the PM Terminal applet which is supplied with OS/2
2.x.  These changes are available in OS/2 2.1 or from the Softronics Bulletin
Board Service which is listed in the PM Terminal dialing directory.  Some of
the changes made were the ability to download from a system which was using
seven (7) data bits such as CompuServ Information Service (CIS).  This can also
be accomplished by using an eight (8) bit communication session and a seven (7)
bit terminal (video) operating mode.  This is all configured in the PM Terminal
applet.

There has been some confusion about the ACDI interface.  In general, all modem
connections should be defined as STANDARD.  You should not used ACDI unless you
know that you are connecting to an ACDI network interface.  If you need to use
ACDI, you will have to remove the REM statement in front of the SASYNCD*.SYS
statement which is located in the CONFIG.SYS file BUT ONLY IF you have not
installed the asynchronous features of Communication Manager.  If you see the
device drivers ASYNCDDB.SYS or ASYNCDDC.SYS loaded in the CONFIG.SYS file, then
the asynchronous features of Communication Manager have been installed.

SFT0049 is an error message received when there is a fault with ACDI support in
PM Terminal.  Check to see that you do not have the Communication Manager and
the PM Terminal ACDI drivers loaded together in the CONFIG.SYS file.

ΓòÉΓòÉΓòÉ 5.2.16. TERMINAL EMULATOR/2 (TE/2) ΓòÉΓòÉΓòÉ

TE/2 was getting intermittent traps (TRAP000d or TRAP000e) at System Level
XR02000.  This has been resolved at System Level XR06055 or OS/2 2.1.


ΓòÉΓòÉΓòÉ 5.2.17. TimeSet 5.3 ΓòÉΓòÉΓòÉ

In order to use TimeSet 5.3, you must be at System Level XR09999 or OS/2 2.1.
The following DOS Settings must be configured:

TRI-BBS version 4.02 works much better under OS/2 2.1 or OS/2 XR09999.


ΓòÉΓòÉΓòÉ 5.2.19. WILDCAT BBS 3.0 ΓòÉΓòÉΓòÉ

Version 3.0 of this DOS application has been reported to work under OS/2 2.0.


ΓòÉΓòÉΓòÉ 5.2.20. X00.SYS (FOSSIL Driver) ΓòÉΓòÉΓòÉ

If you are at System Level XR02000 you need to place a REM before the VCOM.SYS
in the CONFIG.SYS. If you have system level XR06055 or OS/2 2.1 you can set the
DOS Setting, COM_DIRECT_ACCESS, to ON.  The author of the X00.SYS fossil driver
has an OS/2 version available.


ΓòÉΓòÉΓòÉ 6. USING THE MODE COMMAND ΓòÉΓòÉΓòÉ

This section will give a summary of how to use the MODE command.  More
information about the MODE command can be obtained from the OS/2 Command
Reference.


ΓòÉΓòÉΓòÉ 6.1. MODE COMMAND SUMMARY ΓòÉΓòÉΓòÉ

Use MODE from an OS/2 Command line or DOS command line and set IDSR, ODSR, and
OCTS equal to OFF.  For example:

MODE COM3:9600,N,8,1,OCTS=OFF,ODSR=OFF,IDSR=OFF

sets COM3 to 9600, no parity, 8 data bits, 1 stop bit, OCTS, ODSR and IDSR to
OFF.

If OCTS and/or ODSR are set to ON, the COM port will not transmit data unless
CTS and/or DSR signal lines are enabled.  If set to OFF, the COM port will
transmit regardless of the state of signal lines CTS and/or DSR.

If IDSR is set to ON, the COM port will discard the incoming data unless DSR
signal line is enabled.  If set to OFF, the port will receive data regardless
of the state of DSR.

If any problems transmitting or receiving, set OCTS=OFF, ODSR=OFF, IDSR=OFF to
ensure that the hardware connected to the COM port is not preventing the port
from transmitting or receiving.

If an application appears to experience data loss, you can try setting OCTS=ON
and RTS=HS.  This will force the COM.SYS to hardware handshake with the port.
You can also use XON=ON if the application and devices support software
handshaking.

The MODE command at System Level XR02000 is broke; it shows the BUFFER=N/A even
though a 16550AFN buffered UART communication processor is  present.  This
problem was corrected at System Level XR06055.


ΓòÉΓòÉΓòÉ 7. ACDI COMMUNICATIONS UNDER OS/2 2.X ΓòÉΓòÉΓòÉ

This section will give a brief summary of using ACDI communications under OS/2.
You can get more information from the COMMUNICATIONS MANAGER CONFIGURATION
GUIDE (IBM publication number S04G-1002-00)


ΓòÉΓòÉΓòÉ 7.1. ACDI COMMUNICATIONS SUMMARY ΓòÉΓòÉΓòÉ

The COMMUNICATIONS MANAGER CONFIGURATION GUIDE (IBM publication number
S04G-1002-00) describes ACDI as an IBM supplied interface that incorporates
high level functionality (link establishment, disconnect, etc.), and a low
level device  driver that can be called from application programs.
Communication Manager supplies two device drivers, asyncddb.sys and
asyncddc.sys, that are used to provide serial communication capabilities to
applications  that support ACDI API calls. Communication Manager also supplies
an asynchronous Terminal Emulator that utilizes ACDI API calls. These drivers
work independent of com.sys that is supplied as part of the OS/2 base system,
in that, ACDI API calls invoke the asyncddc.sys driver which communicates with
the serial port hardware, and non- ACDI API calls invoke the com.sys driver
which then communicates with the serial port hardware.  At the termination of a
given session the current driver relinquishes control of the serial port
hardware.

PM Terminal, supplied to IBM by Softronics, also provides a facility to use the
ACDI API's available from the Communications Manager supplied device drivers
(asyncdd*.sys). In the event that Communications Manager is not loaded, and one
wishes to use the ACDI function in PM Terminal, Softronics has included a
device driver, sasyncdb.sys, that uses the ACDI API calls, and is capable of
communicating with the serial port hardware.

If using Communication Manager on a system with com port hardware that is DMA
capable, and asynchronous support was selected at installation, APAR JR06199 is
applicable. The fix requires a modified version of asyncddc.sys.


ΓòÉΓòÉΓòÉ 8. CUSTOMIZING THE PM TERMINAL APPLET ΓòÉΓòÉΓòÉ

This section will describe how to customize PM Terminal for your modem.  This
section will also describe how to configure PM Terminal for downloading files
from seven data bit connections such as CompuServ Information Services (CIS).

The PM Terminal is designed to be an object oriented system.  The session you
select from the main menu is composed of Terminal, System Environment,
Connection Path, Modem, Telephone Network and File Transfer objects.  A session
has one of each object.  The most difficult part of configuring PM Terminal is
the definition of the Modem and Video objects.  Once the low level objects (i.e
Modem) are created, a session profile is easily customized by selecting the
various object modules from a list.  This document will give a step by step
procedure for creating a standard 14.4kb Hayes compatible modem session.  You
can use this procedure for any baud rate.


ΓòÉΓòÉΓòÉ 8.1. PM TERMINAL CUSTOM MODEM CONFIGURATION ΓòÉΓòÉΓòÉ

After the creation of the Session Profiles, you may need to close PM TERMINAL
and restart it.


ΓòÉΓòÉΓòÉ 8.2. PM TERMINAL CIS SESSION ΓòÉΓòÉΓòÉ

There is a problem downloading files from any communication session which is
not a default of eight data bits, one stop bit and no parity (8N1).  CompuServ
Information Service (CIS) is an example of such a session.  This is the work
around for the problem:

14. Enter the name CIS TERMINAL for the name.

15. Select the SAVE button using the LMB.

16. Select the CLOSE Button using the LMB.

17. Select the CLOSE button using the LMB.

18. Either select the CIS session which is supplied with PM Terminal or use one
    you created using the steps defined above in step one.  If you are using a
    custom session, remember that the communication session MUST BE defined for
    eight data bits, one stop bit and no parity (8N1). For this example, we
    will use the predefined CIS Session.

19. Select the CIS session by clicking once with the LMB.

20. Using the Left Mouse Button (LMB), select the Session menu bar.

21. Select the CHANGE menu option using the LMB.

22. Under the TERMINAL EMULATION PROFILE, click with the LMB on the List Box
    button (arrow) to display choices.

23. Select CIS TERMINAL from the select displayed using the LMB.

24. Under the CONNECTION PROFILE, click with the LMB on the List Box button
    (arrow) to display choices.

25. Select a Connection Profile which uses 8 data bits, one stop bit and no
    parity.  This could be the custom one you created in the previous section
    (i.e. COM - Standard).

26. Select the OK button using the LMB.

27. Select the SAVE button using the LMB.


ΓòÉΓòÉΓòÉ 9. INTEL SATISFAXTION 400 (internal) FAX/Modem ΓòÉΓòÉΓòÉ

This section will describe how to configure the INTEL SatisfaxTion 400
(internal) modem under OS/2 2.0 and OS/2 2.1.  Some of this will apply to the
external version as well.


ΓòÉΓòÉΓòÉ 9.1. INTEL SATISFAXTION HARDWARE DESCRIPTION ΓòÉΓòÉΓòÉ

The Intel SatisFaxtion Model 400 FAX/Modem differs from typical ISA internal
FAX/Modems in that it does not have a physical UART on board, instead, an
onboard micro-controller emulates the UART function using software. More
detailed information can be found on the INTEL Support Bulletin Board at (503)
645 - 6275.

RELATED INFORMATION:

SMRTUART.TXT

HINT12.TXT


ΓòÉΓòÉΓòÉ 9.2. SMRTUART.TXT file from the INTEL BBS ΓòÉΓòÉΓòÉ

The following section is taken from an information file that is available on
the Intel Support BBS at [phone] (filename=SMRTUART.TXT).  IBM provides
this information with no warranty or support implied for any listed products.
By providing this information, IBM is not implicitly or explicitly endorsing
any products which may be mentioned nor does IBM necessarily agree with any
statements made in the SMRTUART.TXT document.


ΓòÉΓòÉΓòÉ 9.2.1. SATISFAXTION 400 SMART UART OVERVIEW ΓòÉΓòÉΓòÉ

Both the SatisFaxtion 200 & 400 fax modems have a large gate array device which
in addition to other functions, provides special  circuitry that appears to the
PC processor as a standard 16450  compatible serial port.  In reality, it's
just a facade that looks  just like a serial port.  Instead of shifting the
character bits  serially in from and out to a modem on the far end of an RS-232
cable,  the characters stay intact as bytes.  These characters are transferred
directly between the PC processor and the SatisFaxtion 200 and 400  80C186-16
on- board processor through the silicon.  The special circuitry inside the
device gives the 80C186-16 complete visibility and control of the 16450 facade
internal workings.  The 80C186-16 knows what the PC processor is doing on the
other side of this facade, and more importantly, has direct control over what
the PC processor sees.

On the SatisFaxtion 400, since the on-board 80C186-16 knows whether or not the
PC processor has taken the last character that it deposited into the 16450
interface, it will NEVER try to put another character in until the previous one
is read -- no data is spilled.  Think of it as a really smart faucet that shuts
off the water if you don't replace the cup in time.  This is true no matter how
fast the data is being moved or how busy the PC processor is.  The on-board
80C186-16 will wait indefinitely until the PC processor has taken the last
character before trying to give it a new one.

This protection against data loss enables you to set your communication
application baud rate (DTE rate) as high as you like with no fear of losing
data.


ΓòÉΓòÉΓòÉ 9.3. HINT12.TXT file from the INTEL BBS ΓòÉΓòÉΓòÉ

The following sections are from a file on the INTEL BBS which answers questions
about using the INTEL FAX/Modem products under the OS/2 environment.  IBM
provides this information with no warranty or support implied for any listed
products.  By providing this information, IBM is not implicitly or explicitly
endorsing any products which may be mentioned nor does IBM necessarily agree
with any statements made in the HINT12.TXT document.


ΓòÉΓòÉΓòÉ 9.3.1. INTEL SATISFAXTION 400 AND OS/2 2.x ΓòÉΓòÉΓòÉ

ALL OF OUR SATISFAXTION MODEMS CAN BE OPERATED AS A DATA MODEM UNDER OS/2
WITHOUT A PROBLEM.

The one thing to be aware is that the SatisFAXtion Modem/200 and 400 boards
require their device driver to be loaded in a DOS session, then the modem can
be used normally from DOS, Windows or OS/2 applications.  This can easily be
set up as a batch load process.  SatisFAXtion Modem/100 and /400e modems do not
require any additional drivers to be used as data modems under OS/2.

For FAXING, our SatisFAXtion drivers can be loaded and run from a DOS session
under OS/2, but this does not provide faxing directly from OS/2 applications.
However, our testing to date indicates that the SatisFAXtion Modem/100 & 400e
do not fax reliably from a DOS session under OS/2; these products will require
a third party  OS/2 fax driver for Class 1 devices (such as that available from
SofNet) to be used for faxing under OS/2.

We do NOT provide an OS/2 DLL with any of our products for faxing within OS/2's
native environment.  Customers looking for such a driver can contact SofNet at
[phone].

Note:  When running DOS apps in the background, neither FAX nor MODEM programs
       work reliably under OS/2.  For best results always run DOS communication
       applications in the foreground.


ΓòÉΓòÉΓòÉ 9.3.2. WHY DON'T YOU PROVIDE COMPLETE OS/2 SUPPORT IN THE BOX? ΓòÉΓòÉΓòÉ

WHY DON'T YOU PROVIDE COMPLETE OS/2 SUPPORT IN THE BOX?

Because we prioritize our development projects and feature enhancements based
on customer interest and demand.  While OS/2 support is certainly climbing up
the list, to date our customers have put greater emphasis on other requests.


ΓòÉΓòÉΓòÉ 9.3.3. DON'T OTHER FAXMODEM VENDORS PROVIDE OS/2 SUPPORT? ΓòÉΓòÉΓòÉ

DON'T OTHER FAXMODEM VENDORS PROVIDE OS/2 SUPPORT?

We don't know of any desktop faxmodems today that are including software for
faxing from OS/2.  To date such support is only available for desktop faxmodems
as an add-in third party product from a company such as SofNet.


ΓòÉΓòÉΓòÉ 9.4. INSTALLING THE INTEL SATISFAXTION 400 SOFTWARE UNDER OS/2 ΓòÉΓòÉΓòÉ

The following sections will describe how to install the INTEL supplied software
under OS/2.  There are some differences between OS/2 2.0 and OS/2 2.1.  Please
refer to the appropriate section.


ΓòÉΓòÉΓòÉ 9.4.1. PREREQUISITES FOR INSTALLING THE INTEL SUPPLIED SOFTWARE ΓòÉΓòÉΓòÉ

 1. Intel makes available software updates on their BBS (503 645-6275). At the
    time of this writting, an update for the model 400 SatisFaxtion was
    available (filename=29.EXE, 481,455 bytes, 5/18/93). This file is
    self-extracting and contains updates to several component files required
    for the procedures outlined in the following sections.

 2. Unlike most FAX/Modem adapters, the Intel SatisFaxtion 400 (internal ISA)
    FAX/Modem adapter requires the use of two different base address/IRQ
    combinations. One combination is required for the modem portion, while the
    second is needed for the FAX function.  The installation software supplied
    with the unit will set the FAX side of the adapter to a default base
    address of 0350h and set the physical Interrupt Request Level to IRQ10. For
    most OS/2 installations this will be satisfactory.  Should you require
    different settings, please consult the INTEL documentation for further
    information.  You will need to know the I/O address and IRQ later in the
    installation process so keep a record of what is configured.

 3. The installation software may set the modem side of the adapter to "off",
    or to a combination already in use. A utility supplied with the adapter
    (SETUP.EXE) will allow you to change the values for the modem side. If your
    system has an existing COM1 and COM2 port, we suggest that you choose the
    the COM3 option with the IRQ5 value if you do not have a 2nd physical
    parallel port (LPT2) installed. In the case where you do have two parallel
    ports (LPT1 & LPT2), and two serial ports (COM1 & COM2), you MUST disable
    either the second parallel port (LPT2) or one of the existing serial ports
    to install this adapter card. You may then use the IRQ made available for
    the modem side of the SatisFaxtion 400.


ΓòÉΓòÉΓòÉ 9.4.2. INSTALLATION OF BASIC INTEL SOFTWARE UNDER OS/2 2.0 AND 2.1 ΓòÉΓòÉΓòÉ

This section will give some advice on installing the BASIC Intel Software under
OS/2 2.0 and OS/2 2.1.  The installation is basically the same as under native
DOS but there are a few extra steps involved.

 1. Before starting the installation process, make a copy of your AUTOEXEC.BAT
    and the CONFIG.SYS files:

   COPY AUTOEXEC.BAT *.OS2
   COPY CONFIG.SYS *.OS2

 2. Open a DOS session (VDM) and follow the Intel supplied instructions for
    copying the SatisFaxtion software. Since you have made a copy of the OS/2
    AUTOEXEC.BAT and CONFIG.SYS files, you should allow the installation
    utility to update these files.  When you are prompted to remove the
    diskette and reboot the machine, do the following:

    a. Use the CTRL-ESC key to display the window list.
    b. Press the DELete key and select YES to terminate the VDM Session.

 3. Open a VDM and change to the drive and directory where the Intel software
    was intalled.

 4. Copy any Intel update files (see the proceeding section) into this
    directory (and in the case of 29.EXE, type 29 <enter> at the command prompt
    - as the file is un-archived answer yes to overwrite existing files).

 5. Once this is completed, you may have to execute the advanced setup option
    of the Intel supplied utility (SETUP.EXE) to set the base address/IRQ for
    the modem side of the adapter.  Please refer to the INTEL documentation and
    the next section for further information.

At this point, your AUTOEXEC.BAT file will contain statements added by the
installation utility. These are TSR programs needed to run the FAX side of the
adapter. To prevent these programs from being loaded into each DOS session
(VDM) you will need to copy the old files back.  Before you copy the old files,
you must do the following:

COPY AUTOEXEC.BAT FAX400.BAT
COPY CONFIG.SYS CONFIG.400
COPY AUTOEXEC.OS2 *.BAT
COPY CONFIG.OS2 *.SYS

You need to note the IOADDR value in the CONFIG.400 as you will require this
for configuration of VDMs which will require FAX access.


ΓòÉΓòÉΓòÉ 9.4.2.1. RUNNING THE INTEL SATISFAXTION 400 SETUP.EXE PROGRAM UNDER OS/2 ΓòÉΓòÉΓòÉ

This section will give a brief overview for running the SETUP.EXE program. This
example should work for most computers which ONLY HAVE ONE (1) PARALLEL port
and TWO (2) SERIAL ports.  Should you have a different hardware configuration,
please consult the INTEL documentation.

 1. Open a DOS session (DOS command prompt), change to the drive and directory
    where the Intel SatisFaxtion software was installed.

 2. Type SETUP <enter>. After the SETUP screen appears press enter. At the red
    screen type "C" to continue.

    Note:  you can ignore the message which states that SETUP.EXE is unable to
           access the SATISFAXTION driver.

 3. At the "Options Menu" select the entry labeled "Advanced Setup".

 4. At the "Advanced Setup" menu select the "Set-up Hardware" entry.

 5. At the "Set-up Hardware" menu select the "Modem I/O, Interrupt" entry.

 6. Choose one of the 7 entries (the 5th entry being the recommended COM3/IRQ5
    combination for systems that have two serial ports - COM1 and COM2) and
    press enter.

 7. When you have returned to the "Set-up Harware" menu press F10 to update the
    adapter card EEPROM.

 8. The "ESC" key will bring you back to the "Options" menu where you should
    select "Exit setup". You will be prompted with "Are you sure?" to which you
    should reply yes.

 9. The next screen will ask if you wish for your AUTOEXEC.BAT and CONFIG.SYS
    files to be updated. Select "Quit" (without update).

    Note:  If you update the AUTOEXEC.BAT OR CONFIG.SYS files, the procedures
           outlined in this document will not work correctly.  We recommend
           that you always keep a working copy of the CONFIG.SYS and
           AUTOEXEC.BAT files in a safe place.

10. The SETUP.EXE utility then replys with "Press any key to reboot". When you
    are prompted to reboot the machine, do the following:

    a. Use the CTRL-ESC key to display the window list.
    b. Press the DELete key and select YES to terminate the VDM (SETUP.EXE)
       Session.

11. You should now be back at your desktop.


ΓòÉΓòÉΓòÉ 9.4.3. SETTING UP THE MODEM OPERATION OF THE INTEL SATISFAXTION 400 ΓòÉΓòÉΓòÉ

Once the software has been installed, and the modem port configured, it is
necessary to load a device driver that Intel supplies before accessing the
modem. This device driver, SATISFAX.SYS, is a DOS based driver that initializes
the adapter card and must not be loaded in the OS/2 CONFIG.SYS file. The
SATISFAX.SYS device driver must be loaded into every Virtual Dos Machine (VDM)
session which needs access to the INTEL Satisfaxtion 400.

The following procedure will create a program object that will load the device
driver from the startup folder each time OS/2 is started.  You can also use
this object as a template for all VDM sessions which will require access to the
INTEL Satisfaxtion 400.

 1. Open the Startup folder.

 2. Drag a "Program Template" into the startup folder.

 3. Enter a "*" in the "Path and File Name" field.

 4. Enter "/C EXIT" in the "Parameters" field.

 5. Enter "X:\FAX" in the "Working Directory" field.

    Note:  X: is the drive letter you specified during the software
           installation.

 6. Turn to the "Settings" page.

 7. Click on the "DOS Window" radio button.

 8. Click on the "DOS Settings" button.

 9. Enter "X:\FAX\SATISFAX.SYS IOADDR=0350" in the DOS_DEVICE field.

    Note:  X: is the drive letter you specified during the software
           installation.

    Warning: Make sure that the IOADDR value is what is loaded in the
    CONFIG.400 file which you previously saved.

10. Click on "Save"

11. Select the "General" page.

12. Give the object a meaningful name (ie. "Modem Initialization").

13. Close the Settings Window.

After performing these steps, shutdown OS/2 and then reboot to continue. After
rebooting the modem should be available to application programs. For OS/2
commuications applications it is only necessary to specify the port (COM3 if
the above suggestions were followed).

For DOS based communications programs, specify the port/IRQ combination using
the facility provided by the application.  Refer to the application manual and
ISA AND OS/2 SUMMARY:


ΓòÉΓòÉΓòÉ 9.4.4. SETTING UP THE FAX OPERATION OF THE INTEL SATISFAXTION 400 ΓòÉΓòÉΓòÉ

Operation of the FAX side of the adapter requires a FAX application program
such as Intel's FaxAbility (Windows based) or FAXWORKS (OS/2 based). FAXWORKS
supplies an OS/2 based device driver that will operate with the SatisFaxtion
400. FaxAbility require the Intel supplied TSR's be loaded into the DOS session
that FaxAbility is being run from. This is accomplished differently for OS/2
V2.1 and OS/2 V2.0.


ΓòÉΓòÉΓòÉ 9.4.4.1. INSTALLING THE FAXABILITY SOFTWARE UNDER OS/2 2.X ΓòÉΓòÉΓòÉ

The installation of the Intel FaxAbility software under OS/2 is identical no
matter which version of OS/2 you are running.  The setting up of the ICONS,
however, is somewhat different.  We shall provide a method we know to work
reliable but this is not the only way for the software to be installed.  Each
user will have to customize the DOS batch files for the unique environment.

You need to initialize the Intel Satisfaxtion modem before loading WIN-OS2. The
following procedure is to be followed:

 1. Open the startup folder and make a COPY of the "Modem Initialization"
    object you previously created.  You may place the copy on the desktop or
    any folder of your choosing.

 2. Open the Settings Notebook of this new object and erase the PARAMETERS and
    WORKING DIRECTORY fields.

 3. Select the SESSION tab and choose DOS FULL SCREEN.

    Note:  You must use a DOS FULL SCREEN session for this procedure otherwise
           the results will be unpredictable.

 4. Select the GENERAL tab and name this new object "FaxAbility".  We will now
    refer to the object as the FaxAbility Icon.

 5. Close the settings notebook.

 6. Double Click on the (new) FaxAbility Icon which should bring you to a full
    screen DOS command prompt.

 7. Run the FAX400.BAT batch file which you previously created.

 8. Enter WINOS2 and press the enter key.

 9. You should now be at the WIN-OS2 desktop.  At this point you need to follow
    the Intel Supplied instructions for installing the FaxAbility application.
    The installation will procedure just as it would under native MS Windows
    3.x.

After the installation of the software is complete, you will need to refer to
the appropriate section (depending on the version of OS/2 2.x) for creating an
ICON on the OS/2 desktop.


ΓòÉΓòÉΓòÉ 9.4.4.2. CREATING A FAXABILITY ICON UNDER OS/2 2.0 ΓòÉΓòÉΓòÉ

There is a special procedure to load TSRs with Windows based programs under
OS/2 2.0.  This procedure is not required under OS/2 2.1.  This section will
explain how to create an ICON on the desktop.  This is only an example and you
might have to change things such as drive letters and paths.  This example
could be used for other DOS and WINDOWs applications which require access to
the Intel Satisfaxtion modem.

 1. You will need to make a copy of the FAX400.BAT file which you previously
    created.  Copy this file to a file named:  WFAX400.BAT.

    Example  copy FAX400.BAT WFAX400.BAT

 2. Use the System Editor (E.EXE) to edit the WFAX400.BAT file.  You have two
    options:

    a. You can just start a WIN-OS2 full screen session or
    b. You can start the Intel FaxAbility program "seamlessly"

The following figures will give you an example of what your WFAX400.BAT should
look like.  The PATH setting may be different depending on where you have
loaded the software.

To setup the FaxAbility Icon (which you previously created), you need to modify
the object's Settings:

 1. Open the settings notebook and enter the following fields:

   o PATH & FILENAME: d:\faxablty\manager.exe
   o PARAMETERS:
   o WORKING DIRECTORY:  d:\faxablty

 2. Select the SESSION tab and select WIN-OS2 Full Screen from the options
    presented.

 3. Click on the WIN-OS2 (DOS) Settings button to configure the session.

 4. Select the DOS_DEVICE option from the list and make sure that the
    SATISFAX.SYS device driver is loaded.

 5. Select the DOS_SHELL option and set the shell command to the following:

    C:\OS2\MDOS\COMMAND.COM C:\OS2\MDOS /K WFAX400.BAT

 6. You may also need to set some of the other settings for better performance.
    (DOS PERFORMANCE ISSUES)

 7. Select SAVE to save the settings.  Close the object.

You should now be able to double click on the FaxAbility Icon and start the
program.

ΓòÉΓòÉΓòÉ 9.4.5. FAXWORKS, INTEL SATISFAXTION AND OS/2 ΓòÉΓòÉΓòÉ

ΓòÉΓòÉΓòÉ 9.4.5.1. Comments from a Fernwood BBS SatisFaxtion 400 User ΓòÉΓòÉΓòÉ

The best fax modem for OS/2 users is, probably, the Intel Satisfaxtion 400, a
14.4KB fax and data modem with co-processor on board. Co-processed faxing is
ideal for a multi-tasking environment.

The problem is that Intel rather emphatically says that it does not support
OS/2 and gives little help to callers trying to use their modems under OS/2. So
let me outline a couple of points I've learned playing with the modem, OS/2 and
several fax, communications and BBS packages.

The only place where Intel's lack of support for OS/2 has much impact is in the
configuration process. The modem works perfectly well with all the  OS/2
packages I've tried it with. Normal DOS installation creates two files,
Download.400 and Loader.400, which are downloaded to the modem and work
perfectly well under OS/2. The only tricky part is the DOS "SetUp" program in
the supplied diskettes. This program scopes out your system and assigns I/O
addresses and COM ports for fax and data respectively. You can run Setup under
OS/2 DOS on some machines without difficulty. Type "Setup noreboot" at the DOS
prompt.

If Setup has trouble configuring the modem under OS/2 DOS, which happens, you
can use Boot Manager or Dual Boot to boot up real DOS and configured the modem
that way.

My notebook, however, runs only OS/2 HPFS and Setup, run under OS/2 DOS, could
not find a com port for the data modem. It insisted on turning the modem off. I
tried configuring the modem under real DOS on a much different machine and
forcing the values I thought might work on my notebook.  The data modem would
not function when I installed it with those settings on my notebook. (Intel's
tech support had told me that the results of my unsuccessful attempts to find
correct com port settings for the data modem meant that it would not run under
OS/2 on that notebook system.)

But if I have learned anything about OS/2, it is that you should never give up.
There is almost always another way to do anything. So I tried the following: I
created a 3 1/2 inch DOS boot disk and copied the files from Intel's first 5
1/4 installation diskette onto it. I booted DOS from the floopy and ran Setup
from the A: drive. Since I use HPFS, the system did not know about the C: drive
and I could not perform some functions that required a C:\ drive directory. But
Setup did work perfectly in assigning addresses and ports. I also used Advanced
Setup to configure answering mode, etc. Just stay out of any line that prompts
for a hard drive directory. You will have to reboot to get out again. When I
had finished configuring the modem, Setup wrote the settings to the modem's
non-volatile RAM. I then aborted Setup and rebooted OS/2. The modem worked!

Once you have configured the modem itself, you just get copies of the two *.400
files supplied (in a *.zip file) on the installation diskette and put them in
you FaxWorks directory. You will need to start up FaxWorks in receive mode each
time you reboot your system in order to download these files to the modem.

One of the great things about the Satisfaxtion 400 is that it will allow you to
run both fax and data from the same line without juggling the software. In
other words, you can fire up your communications software and access the data
modem while FaxWorks is still running in receive mode. (Obviously, you can't
fax and modem at the same time.)

Intel documentation describes a setting of the modem, when it is the sole owner
of a phone line, which allows it to answer the phone, listen for a fax, then
send out data modem mating signals for a few seconds and then switch back to
fax mode again. In theory, this allows it to answer incoming autodial fax
calls, manual dial fax calls and autodial modem calls in the appropriate modes.

I tried this with the OS/2 version of the Maximus BBS. The modem was set up to
answer on one ring and to own the phone line. FaxWorks was set up to receive on
the first ring. Maximus was in the default mode: S0=0 and the BBS software
ready to send ATA after one RING.

That does not work. S0 must be set to a number greater than 0 or the modem will
not attempt to recognize incoming data calls. So I set S0=1 in the
initialization string the BBS sends out to the modem and set the BBS  to the
alternative mode where it responds to the modems autoanswer feature. This half
worked. All fax calls were answered as faxes. But modem calls were answered as
data calls only until the first fax call came in. After the first fax call, the
modem treated all calls as fax calls, until I manually reinitialized the modem
by killing and restarted Maximus. Obviously, FaxWorks was reinitializing the
modem and setting S0 back to 0, the factory default. So I changed the
Initialization string in Maximus by adding "&W&Y" to the end of the string.
"&W" stores the configuration in the first of two places in the modem's memory.
I figured that FaxWorks probably issued an "ATZ". To be on the safe side, I
also added "&Y" which instructs the modem to use the programmed settings at
startup.

This worked! Here is what happens. The modem picks up at the first ring and
listens for a fax tone. If it hears one it tells FaxWorks to pick up. If it
does not here a tone, it answers as a modem and tries to handshake. If it
succeeds, it tells Maximus to pick up. If it cannot handshake, it sends out fax
tones and tried to connect as a fax again.

I have each software package configured to turn on the modem's speaker until a
connection is established. Each is set at a different volume so I can  hear
what is going on.

If the call is a fax call, the speaker becomes active at the volume set in
FaxWorks only after the modem hands the call to FaxWorks. It acts, in other
words, just as if FaxWorlks had picked up the call itself. If the call is a
modem call, the speaker becomes active at the volume set in Maximus, but only
after the modem hands the call to Maximus.

I now have my office's EMail & File Transfer BBS and main fax all coming in on
the same phone line to my desktop computer running OS/2. This integrates Email
and file transfer with fax communications. I can also use my own BBS to
retrieve faxes on the road.

I intend to install the multi-line version of FaxWorks when it becomes
available and run a two line fax and two node Maximus BBS from the same two
phone lines and modems.

The DOS_DEVICE (COMDD.SYS) may not be the only one required depending on the
application.  (For example, Intel's SatisFAXion board requires a device driver
loaded into each VDM which will use that adapter). The COMDD.SYS driver is
usually required only for older DOS communication applications.  Do not use
COMDD.SYS for  EVERY DOS  communication session; use it only if it  resolves
the problem.
