-
- RUNNING WINFAX PRO V3.0 UNDER OS/2 2.1
-
-
- SYMPTOMS:
-
- 1. WinFax Pro v3.0 is compatible with OS/2 2.1, but you must
- first call the Vendor for the Service Release.
-
- 2. Since Windows exists in other than the Microsoft version,
- WinFax Pro may not run with OS/2 for Windows.
-
- OS/2 2.1 is a multitasking operating system that allows
- Windows or DOS applications to access the serial ports 1000
- times per second. This is not frequent enough to allow
- reliable data transfer. There is a special UART* that has
- the buffering capability to allow reliable data transfer.
- OS/2 2.1's serial port driver uses the buffering capability of
- this UART to increase the reliability of data transfers
- running at 9600 baud or higher. The type of UART is known as
- 16550A. To send or receive data at 9600 baud reliably under
- OS/2, the serial port the fax modem is connected to must
- have a 16550A** UART.
-
- Internal modems have their UARTs built onto the modem card.
- Many of the high speed internal modems are equipped with
- 16550A UARTs. External modems use an existing serial port in
- the computer. Most of these ports use 16450 UARTs.
-
- If either the internal modem or the computer's serial port
- does not allow for the upgrade of the existing UART to a
- 16550A, then SIO drivers may help.
-
- If the modem or serial port is not equipped with a 16550A
- UART, the SIO drivers, which are shareware, are on OS/2
- BBS's and on Compuserve in the OS/2 file section.
-
- Version 1.02 was used in testing WinFax.
-
- 3. When these drivers are installed, some of the WIN-OS/2
- settings are removed and replaced with other settings.
-
- 4. SIO drivers are third party drivers. For OS/2, they may
- require changes to the CONFIG.SYS to disable the use of the
- original COM.SYS and VCOM.SYS.
-
- 5. The SIO drivers enhance the performance of DOS and Windows
- applications running under OS/2 2.1 by:
-
- A. Emulating a 16550 UART through software if one is not
- installed.
- B. Allowing DOS and Windows applications to make better use
- of the 16550A UART if one is installed. With a 16550A
- UART and WIN-OS/2 settings, the drivers do not need
- to be used for WinFax. If you still have problems after
- changing the settings, the SIO drivers may help.
-
- A UART is essentially the heart of a serial port. It
- controls the transmission and reception of data to and
- from the computer. The 16550A UART can hold up to 16
- bytes of information between port scancs whereas a
- conventional UART cannot hold more than one byte. The
- original 16550 had a bug in its handling of its 16 byte
- buffer. The 16550A corrected this.
-
- The 16550AFN and 16550AF UARTS are revised versions of
- the 16550A UART. They work with the settings below.
-
-
-
- RESOLUTION:
-
- 1. For Class 1 or 2 modems, change WIN-OS/2 settings as
- recommended below and edit SYSTEM.INI under .386Enh. section
- as indicated.
- 2. Note procedures for setting the baud rate.
- 3. Note procedures for using SIO drivers if the need arises.
- 4. WinFax Pro should run in full screen session and be left
- running in the foreground.
-
-
-
- PROCEDURES:
-
- 1. WIN-OS/2 Settings:
- COM_HOLD to ON
- HW_TIMER to ON
- INT_DURING_IO to ON
- IDLE_SENSITIVITY to 100
- IDLE_SECONDS to 60
-
- NOTE: IDLE_SENSITIVITY and IDLE_SECONDS may vary between
- systems, and in many cases can be left to default
- values.
-
- 2. A. For 14400 BPS fax modems, edit SYSTEM.INI in the .386Enh.
- section as follows:
-
- COM?FIFO=0
- where ? is the com number being used.
-
- B. If running in an Enhanced Mode Windows session under OS/2
- 2.1, edit SYSTEM.INI in the .386Enh. section as follows:
-
- COM?BUFFER=4096
- COMBOOSTTIME=30
- where ? is the COM number being used.
-
- 3. With a Class 1 fax modem and a version of WinFax dated April
- 1993 or later, WinFax allows for speed restrictions on both
- transmissions and receptions. For send sending or receiving
- faxes at 9600 baud or above, edit the General section of
- the WINFAX.INI as follows:
- A. The example is for 7200 bps transmitting and 4800 bps
- receiving:
-
- MaxTXspeed=7200
- MaxRXspeed=4800
-
- B. Valid entries for MaxTXspeed are 14400, 12000, 9600, 7200
- and 4800 bps.
- C. Valid variables for MaxRXSpeed are 14400, 9600, 4800 baud.
- NOTE: 1. To find the version date of WinFax, select Help,
- then About from the main WinFax screen.
- 2. There is an update if the WinFax version is
- January 1993 or earlier.
-
- 4. For SIO drivers, REM lines in CONFIG.SYS that refer to COM.SYS
- and VCOM.SYS.
- NOTE: Original serial port drivers should be REMed because
- the SIO drivers aren't an exact replacement for the
- serial port drivers shipped with OS/2 2.1.
-
- 5. WinFax may not install properly if the SIO drivers are
- running. If this is the case REM the SIO drivers to enable
- the original serial port drivers. Once installation is
- completed, REM COM.SYS and VCOM.SYS, then unREM SIO drivers.
