OSBPFAXW - FAXWORKS LITE PROBLEM - OS/2 WARP BONUSPAK
01/23/96
=======================================================================
FaxWorks Lite Problem--OS/2 Warp BonusPak
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
When using FaxWorks Lite from the OS/2 Warp BonusPak, the following
error message is received:
FMD <port number> not responding.
RESOLUTION
The problem can be caused by one of the following:
* The serial port is not set up for OS/2 Warp.
* The FaxWorks device driver is not set up for the serial port.
* FaxWorks is not set up correctly.
* The data/fax modem does not support FaxWorks.
The Serial Port Is Not Set Up for OS/2 Warp
-------------------------------------------
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 interrupt requests
(IRQs) and I/O addresses.) FMD.SYS and COM.SYS use the same format, and
their parameters must match the physical settings of the serial adapter
or internal modem. The IRQ and I/O addresses are determined by the
actual device (the internal modem) and NOT the OS/2 device driver.
To determine the I/O addresses and IRQs on an ISA-bus system, compare
the actual settings for the device with those listed in the
documentation that comes with the device. For example, if an internal
modem is present at I/O address 03e8h, is set up to use IRQ 5, and is
the third port (COM3), the CONFIG.SYS file should have the following
statements for COM.SYS and FMD.SYS:
DEVICE=C:\OS2\BOOT\COM.SYS (3,03E8,5)
DEVICE=C:\FAXWORKS\FMD.SYS L (3,03E8,5)
You can use the MODE command to verify that the port has been set up
correctly for OS/2 operation. (The MODE command is described in the
Command Reference, which is in the Information folder.) The COM.SYS
device driver recognizes the presence of a serial device if the MODE
command does not return an error. If the MODE command works, you can
try the following test. At an OS/2 command prompt, 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 set up correctly for OS/2 Warp. If it
fails, there is probably a hardware conflict or configuration error.
The FaxWorks Device Driver Is Not Set Up for the Serial Port
------------------------------------------------------------
The FaxWorks Device Driver (FMD.SYS) uses the same parameters as the
COM.SYS device driver, but also requires the L parameter. See the
FAXWORKS\README.DOC file for a description of these parameters.
FaxWorks Is Not Set Up Correctly
--------------------------------
Review the modem settings in the FAXWORKS\README.DOC file. FaxWorks
Lite works better with the Class 1 fax standard. If your modem is set up
for the Class 2 standard, try setting it up for the Class 1 standard.
Note: Do not check the USE HW FIFO setting unless the MODE command
returns BUFFER=AUTO.
The recommended settings for Class 1 fax modems are:
BAUD: 9600
CLASS: CLASS1
FEATURES: CHECK TCF SIGNAL
RECEIVE EOP DELAY
USE HW FIFO (if BUFFER=AUTO)
Notes:
1. Any valid port address and IRQ should work. Some 14.4K data/fax
modems have problems trying to fax at 14.4K. Make sure the modem
works at 9600 baud before increasing the BAUD value.
2. HW FIFO refers to the compatibility of hardware with the NS16550a
UART. To determine compatibility, use the MODE command and look at
the BUFFER setting. If it is set to N/A, the hardware is not
compatible with NS16550a.
The Data/Fax Modem Does Not Support FaxWorks
--------------------------------------------
FaxWorks Lite supports only data/fax modems that are compatible with
NS16450 and NS16550a. It does NOT support serial devices, such as
Intelligent Digiboards, Hayes ESP devices, and Intel Satisfaction
(internal) modems. See the FAXWORKS\README.DOC for more information.
