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 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.
