Go to Ports, remove any COM ports defined other than a COM port which the mouse may be using. Go to Other Devices (if that group appears), remove any modems or unidentified cards defined. Remove any listing which contains a yellow exclamation point. When you remove an item, Windows will give a warning to confirm, click OK when the warning appears. 3)Go to Control Panel and Modems, remove any modems which may be defined. If you get the "Add New Hardware Wizard", cancel out and continue to the next step. 4)Shut down Win-95. Turn off the computer. 5)Turn the computer back on, restart Win-95. It should automatically detect the "new" hardware and reconfigure any serial devices. If it asks for a driver from the modem manufacturer, please insert the disk which lists the Win95 modem driver. Let it read the driver from the disk. Do not run the install from that disk. The modem should configure properly. The above may not always work. In some cases Win-95 may fail to detect enabled COM Ports and assign the modem to a COM Port which is in use by the system. If that is the case, everything will look fine in Device Manager but in Control Panel, Modems, Diagnostics, More Info, it will not communicate with the modem. If that happens, remove any modem definitions in Device Manager under either Modem or Other Devices and then from the Start Menu, choose MS-DOS Prompt and once there do the following: 1)Type "Debug" and press enter. That should provide a dash "-". 2)Type "D40:0L8" and press enter. That will give a bunch of numbers which will look basically as follows: 0040:0000 F8 03 F8 02 00 00 00 00 The numbers that matter are the ones starting after the four zeros. To interpret the ports detected, interpret thusly: Address Port Address Port F8 03 COM 1 E8 03 COM 3 F8 02 COM 2 E8 02 COM 4 3)When done type "Q" and press enter to return to a DOS prompt and then type "Exit" to return to Win-95. 4)Go to Control Panel to choose Add New Hardware. A)Click "Next" B)Check "No" and click "Next" C)Select "Ports" and click "Next" D)Manufacturer is "Standard Port Types" and Model is "Communications Port" (those are the defaults). Click "Next" E)It will display an I/O Range. If the I/O range does not match what Debug showed, note the address and the click "Next" F)Click "Finish" G)When asks to shut down, select "No" H)Repeat as necessary 5)If a port in step 4 did not get the proper address, go to Device Manager, select the port, select resources and uncheck "Use automatic settings" and change the resources being used. You may need to change the basic configuration option selected. 6)Once the appropriate number of ports have been added, shut down Win-95, turn off the computer, and then restart the computer. The modem should properly configure. The above steps having been taken, supposing the modem still doesn't want to work, the resources may need to be manually changed by going to Device Manager, Modem, selecting the modem, going to Resources and unchecking "Use automatic settings". IRQ's to try are 5, 10, 11, 12 or 15. IRQ 5 is often used by soundcards. 15 by CD-ROM's or network cards. 12 by PS/2 style mice. 10 is also often used by a soundcard. Several different basic configurations may need to be tested before getting an appropriate configuration. 2.2 Win95 not detecting modem except after a reboot or multiple reboots Solution: Please contact Supra Technical Support. Please have your computer model, BIOS type & version, COM port and IRQ, and ROM version ready for a quick response. 2.3 Software can't access modem on COM 5 Reason: Software designed for Windows versions prior to Win-95 may only support COMs 1-4. Solution: See first issue (2.1) about modem not configured properly. If, however, there are four COM Ports in the system or three COM ports and a video card based on the S3 chip set (which uses the 02E8, COM 4, address), then there is nothing you can do to avoid having the modem configure to COM 5 other than having the user disable a COM Port so the modem can reconfigure properly. 2.4 Need to manually reconfigure modem Windows 95 provides an interactive Help file which will walk you through the reconfiguring process. To learn how to modify a modem's COM port or IRQ, please look up IRQ in the Help file found in the START menu. 2.5 Need to use keypad for a mouse In some cases, Windows 95 configured the Modem to the same COM port or IRQ as the Mouse. To reconfigure the modem as described in 2.4 above, you will need to maneuver without the mouse. Solution #1: Hold down the Control key and then press the Escape key: this will open the START menu. Use the down arrow key to move through the START menu, highlight SETTINGS and press ENTER. This opens up a sub-menu and press ENTER again to select CONTROL PANEL. Use the arrow keys to highlight ACCESSIBILITY OPTIONS and then press ENTER. Use the TAB key to maneuver between the tabs at the top of the window and select MOUSE; press the SPACEBAR once to choose MouseKeys. Use the TAB key to select the OK button and then press ENTER. Be sure that the NUM LOCK option is selected on your keyboard and then use these keys to move the mouse cursor: Arrow Keys move the cursor 5 = Click + = Double-Click - = Right Mouse Button / = Left Mouse Button You need to tell it which button you are going to click before "clicking". Solution #2: Use the Hot Keys to maneuver. 2.6 Getting the SupraExpress 288iPnP modem to work in MS-DOS Mode. Option#1 1) Make sure that there is a previous version of DOS on the computer. If this was an upgrade to Windows 95, then there should still be a DOS directory on the computer (assuming that it was not deleted). 2) Open Explorer from the start menu under Programs then choose View, then options. Click "Show All Files". Click the right mouse button on the MSDOS.SYS file in the root directory and choose Properties. 3) Uncheck the hidden and read-only boxes. Click on OK. Double-click on the MSDOS.SYS icon. Open with Notepad. 4) Under [Options] add the line "BootMulti=1" (minus the quotes). 5) Open Explorer again and change the MSDOS.SYS boxes back to what they were at before. Click OK. 6) Shutdown Windows and turn off the computer. When you see the words "Starting Windows 95", press the F8 key. Choose "Boot to previous version of DOS." 7) Install the Plug and Play Utility disk. Choose DOS only install. When the installation reboots the machine, allow it to boot directly into Windows 95. 8) Create a shortcut to the DOS based program by clicking the right mouse button on a blank section of the Windows 95 desktop. Follow the instructions to create a shortcut to the program. When the icon is created, click on the icon with the right mouse button and choose properties. 9) Click on the Program tab. Click on Advanced. Check the MS-DOS Mode, Warn before starting MS-DOS Mode, and Specify a new MS-DOS Configuration boxes. In the boxes that are available for CONFIG.SYS and AUTOEXEC.BAT, enter the following: CONFIG.SYS DEVICE=C:\SUPRA\DWCFGMG.SYS DEVICE=C:\WINDOWS\Himem.Sys DOS=HIGH,UMB AUTOEXEC.BAT SET winbootdir=D:\WINDOWS SET PROMPT=$p$g SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND 10) Click on OK, OK. Now when you double-click on the icon created, you will be told that the program needs to shutdown to MS-DOS mode. Click OK. You machine will reboot and use the CONFIG.SYS and AUTOEXEC.BAT files furnished in the shortcuts settings. When you exit out of that program, the machine will reboot back into Windows 95. If the program used doesn't support higher IRQs then this will not solve the problem. But there is Plug and Play support installed at this point, and COMit for Windows DOES WORK for a modem configured for COM 3, IRQ 5. Option#2 1)Boot into Safe Mode, Command Prompt only. 2)Using the PnP Utility Disk, install the PnP Utility for DOS only. All the default answers to the install's questions are fine. 3)The install program will add the DWCFGMG.SYS (DOS driver for the modem) line to the Win95 CONFIG.SYS file. If it does not, edit the config.sys and add as the first line "device=c:\supra\dwcfgmg.sys" (minus the quotes). 4)Reboot the computer, change to the Supra directory (type CD \Supra and press enter) and then type "WTM" and press enter. Note the I/O address and Interrupt reported by WTM. 5)Confirm the I/O Address and IRQ do not conflict with any devices in the system. The basic PnP software and drivers are loaded at this point. If desired or if either the I/O address or IRQ needs to be modified, install the software on the WinICU disk. Again, boot into Safe Mode, Command Prompt Only and install for DOS only. 3 Windows 3.1x PnP Modem Issues 3.1 DOS Configuration Manager Not Loaded when running Where's The Modem Reason: Generally smartdrv is the culprit. If the computer reboots without smartdrv flushing its buffers, the last changes the install made will be lost. Solution: Add lines which are missing in Window's system.ini file. The System.ini file is found in the \Windows directory. Working from DOS 1)Make sure you have a DOS prompt and are in the \Windows directory. Type "CD \Windows" and press enter to go to the \Windows directory. 2)Edit the system.ini file. Type "Edit system.ini" and press enter. This will load the file and allow you the opportunity to edit the file. 3)Press the Alt-S (hold down the Alt key and press the S key). This provides the Search Menu. Select "Find". For "Find What", type in "386Enh" and press enter. This should position you at the line "[386Enh]". 4)Press the "End" key and then press enter. On the new line type "device=vcmd.386" and press enter. On the next new line type "device=vcad.386". DO NOT PRESS ENTER after typing the second line. 5)Press Alt-F (hold down the Alt key and press the F key). This will open the File menu. Arrow down to Save or press "S" to save the file. Press Alt-F again and this time select the Exit option. 6)Start Windows. The modem should be properly recognized under Windows as well as DOS at this point. Working from Windows 1)Open Notepad (usually in the accessories group). Select "File", then "Open". Notepad will ask for a filename and will probably have " *.txt " in the filename area. Delete the *.txt and type in "system.ini" and press enter. 2)Select "Search", then "Find". For "Find What", type in "386Enh" and press enter. This should position you at the line "[386Enh]". 3)Close the search box and then press the "End" key and then press enter. On the new line type "device=vcmd.386" and press enter. On the next new line type "device=vcad.386". DO NOT PRESS ENTER after typing the second line. 4)Select "File", then "Save" to save the file. Select "File", then "Exit". 5)Close Windows. Restart Windows. The modem should be properly recognized under both DOS and Windows at this point. 3.2 NVS error reported when starting computer Reason: Some PnP BIOS'd machines only have a limited number of NVS entries for modifying devices. The Legacy software may not work with the BIOS. Solution: In some cases the PnP BIOS may be able to be configured to have the BIOS automatically configure the modem. If it does not do it without changing the BIOS. They should contact the computer manufacturer. Otherwise, there is no workaround. Version 4.50PG of the Award BIOS will detect and configure a Supra PnP modem. However, it will not tell you where it is configured. With this BIOS, you will not want to install the PnP Utility disk. If you already have, please go into the Supra directory in DOS and type "uninstal y" without the quotes followed by the enter key. To find where the modem is configured, you can use the "echo" command from DOS. Type the following lines at your DOS prompt. The line which produces a modem dialing, is the one which found the modem. echo ATXDT555>Com1 echo ATXDT555>Com2 echo ATXDT555>Com3 echo ATXDT555>Com4 Once we know what port the modem is on, we can go to Windows and find the IRQ for the modem. If the modem was found on COM 1, the IRQ is likely 4. If the modem is found on COM 2, the IRQ is likely 3. Some other IRQ settings to try are 5,10,11,12, and 15. IRQ 5 is often used by Soundcards. 15 by CD-ROM's or network cards. 12 by PS/2 style mice. 10 is also often used by a soundcard. To find what IRQ the modem is using. Go into the Main program group in Windows. Choose Control Panels. Choose the port which the modem was found. Choose settings/advance and change the IRQ to one of the suggested IRQs. Restart Windows. Go to the Accessories program group and run Terminal. Set the port to the correct port. At the blank screen type AT followed by the enter key. If you get OK back on the screen, you have found the IRQ. If you do not get OK, you will want to try another IRQ. Keep this process going until you find the correct IRQ. 3.3 No ESCD.RF file found when starting computer Reason: Many PnP BIOS'd machines use an ESCD.RF file to maintain the PnP setup information. The Legacy install software checks the address range F000-FFFF for the letters "PnP". If it finds those letters, it assumes a PnP BIOS. Some BIOS's may have those letters yet not be an actual PnP BIOS causing the Legacy install software to not install all needed files. Solution #1: If you have Legacy Installation software v2.2 or later, re-run the installer and when the software shows you the "PNP BIOS DETECTED" screen, select "YES" to use "LEGACY PNP" instead of "BIOS PNP". Solution #2:In the install.dat file there is a line which says at the end "force partial install". At the *start* of that line add "//" (minus the quotes). Save the file then rerun the install. It will prompt as though it is doing a partial install but will actually do a full install. In some cases, in order to get it to work properly even after forcing a full installation, you may need to change the line in the config.sys from "device=c:\supra\dwcfgmg.sys" to "device=c:\supra\dwcfgmg.sys /static". Adding that has worked in several instances where forcing a full install alone has not worked. 3.4 Software cannot find PnP modem - usually DOS software Reason 1: The software does not support non-standard IRQ's and the modem is at a non-standard IRQ. Some DOS software may allow support IRQ's up to IRQ 7 but not support the upper IRQs. Solution 1: Either disable a COM Port so the modem can be configured at a standard address and IRQ or change software to software which will support non-standard IRQs. To disable a COM port, you will need to refer to your computer hardware manual. Reason 2: Software is looking for an entry in the system table to confirm the port exists. Since the modem does not get configured until the system has booted and taken its readings, an entry for the modem's address will not show up in the system table. Solution 2: Option 1) Do a warm boot (Control-Alt-Delete) and it will then show up as the modem does not lose its settings with warm boot. Option 2) Setup a debug file to write the address of the modem to the system table. Steps are as follows: 1)Use MSD or Debug (D40:0L8) to determine the addresses of the COM Ports detected without the modem. To use Debug: A)Type "Debug" and press enter. That should provide a dash "-". B)Type "D40:0L8" and press enter. That will give a bunch of numbers which will look basically as follows: 0040:0000 F8 03 F8 02 00 00 00 00 The numbers that matter are the ones starting after the four zeros. To interpret the ports detected, interpret thusly: Address Port Address Port F8 03 COM 1 E8 03 COM 3 F8 02 COM 2 E8 02 COM 4 C)When done type "Q" and press enter to return to a DOS prompt. 2)Create a file in the root directory ( C:\ ) called "fixcom.deb". You can use Notepad in Windows or Edit from DOS to create this file. The file should have four lines - I would recommend having caps lock on for consistency. A)The first line should be "E40:0" B)The second line depends on what ports are detected without the modem. If COM 1 is detected as either an existing COM Port or as the PnP modem, start with "F8 03 ". If COM 2, add "F8 02 " to the line. If COM 3, add "E8 03 " to the line. If COM 4, add "E8 02 " to the line. For example, if COM 1 and COM 2 are detected and the modem is on COM 3, the line should read "F8 03 F8 02 E8 03" C)The third line is "Q" D)The last line should be blank 3)Insert in the autoexec.bat "debug < fixcom.deb > nul" without the quotes. The arrows are required in order for debug to work properly. 4)Restart the PC. 3.5 Windows not holding address for modem after configuration Reason: Windows looks at the system table and determines there are x number of COM ports. If the system table shows COM 1 and COM 3 and the modem is configured for COM 2, under Windows COM 1 will report properly, COM 2 will show with COM 3's address although you may have used "Where's the Modem" to tell it to put the modem at COM 2. The modem does not get configured until after the system has booted so there is no entry for the modem's address in the system table. 1)Use MSD or Debug (D40:0L8) to determine the addresses of the COM Ports detected without the modem. To use Debug: A)Type "Debug" and press enter. That should provide a dash "-". B)Type "D40:0L8" and press enter. That will give a bunch of numbers which will look basically as follows: 0040:0000 F8 03 F8 02 00 00 00 00 The numbers that matter are the ones starting after the four zeros. To interpret the ports detected, interpret thusly: Address Port Address Port F8 03 COM 1 E8 03 COM 3 F8 02 COM 2 E8 02 COM 4 C)When done type "Q" and press enter to return to a DOS prompt. 2)Create a file in the root directory ( C:\ ) called "fixcom.deb". You can use Notepad in Windows or Edit from DOS to create this file. The file should have four lines - I would recommend having caps lock on for consistency. A)The first line should be "E40:0" B)The second line depends on what ports are detected without the modem. If COM 1 is detected as either an existing COM Port or as the PnP modem, start with "F8 03 ". If COM 2, add "F8 02 " to the line. If COM 3, add "E8 03 " to the line. If COM 4, add "E8 02 " to the line. For example, if COM 1 and COM 2 are detected and the modem is on COM 3, the line should read "F8 03 F8 02 E8 03" C)The third line is "Q" D)The last line should be blank 3)Insert in the autoexec.bat "debug < fixcom.deb > nul" without the quotes. The arrows are required in order for debug to work properly. 4)Restart the PC. 3.6 Computer video errors or locking after running install program Solution: Go into the CMOS and turn of video shadowing. Once it is off, remove and reinstall the PnP software. You may or may not be able to turn it back on after the install is complete. To Remove the PnP software, go into the Supra directory in DOS and type "uninstal y" without the quotes and press enter. 3.7 Using PnP with QEMM When using our PnP modem under DOS or Windows 3.1x, make sure the first line in your config.sys file shows "device=c:\supra\dwcfgmg.sys". QEMM often tries to be listed as the first entry in the config.sys. 3.8 Need to install PnP software to a drive other than C: This is not a supported feature, however, the following process should help. 1.Copy CONFIG.SYS to the drive that windows in on, i.e.: F:\ (this is not always necessary) 2.Edit C:\CONFIG.SYS and manually add the SUPRA line, device=F:\supra\dwcfgmg.sys, on the first line of the config.sys, it will be needed later on - ignore the error you get on boot up since SUPRA is not there as yet. 3.Edit INSTALL.DAT and INSTALL1.DAT on the PnP Utility disk. Change the windows drive and the boot drive to the windows drive letter, i.e.: F 4.Change to the drive where the supra directory is to be found i.e. F: 5.Go through entire install as if drive F was C. 6.When the system reboots the config.sys on C (the real one) finds the supra directory that is on F. 7.Delete the config.sys off of F: (it was only there for dummy reasons) 8.If you need to move the modem location and install the WINICU disk, do the same steps w/drive letters to the INSTALL.DAT and INSTALL1.DAT on the Win ICU Diagnostic disk as well. 3.9 If installing with a clean boot. If installing with a clean boot, do not do a full install. Only install for DOS. Once the Plug and Play software is installed for DOS, please navigate to the Supra directory in DOS. Type WTM followed by the enter key. Note the I/O Address and the IRQ. These are your modems settings. The I/O addres refers to a COM port number listed below. I/O Address COM port 03F8 1 02F8 2 03E8 3 02E8 4 Once you know what COM port the modem is configured to, please run Windows. Navigate to your "Main" program group and double click on "Control Panels". Choose "Ports" and select the port which the modem was configured to. Make sure the address and the IRQ are the same. If not, make the appropriate changes. If these changes do not "stick" to the COM port in the Control Panels, you may have a situation similar to section 3.5. Restart Windows configure each software package to the COM port which the I/O address corresponds to. 3.10 Install software believes it is in a DOS Box when it isn't Before running the install, switch to the floppy disk drive (a: in most cases) once on that drive, you can type install. DO NOT type A:\install all on one line. 3.11 Legacy software will not install or gets stuck at one of the blue screens Option #1 Before you install the software, at a DOS prompt, type smartdrv /x followed by the enter key. Now follow the instructions for the install. Option #2 Either press F5 when the words "Starting MS-DOS" appear on-screen to bypass the config.sys and autoexec.bat files or boot from a clean bootable floppy. Rerun the install. See 3.9 for information regarding a clean boot. A clean bootable floppy is a boot disk without a config.sys or autoexec.bat file. 4 Other Platforms with PnP Modem Issues - Note: These platforms are not directly supported. These are suggestions which may or may not work. 4.1 OS/2 - How to setup a PnP modem Some users of OS/2 and our PnP modems have reported to us that by opening a DOS windows upon booting up OS/2 and running the DWCFGMG.SYS driver for DOS configures the modem and allows the modem to work. This works if your system is setup for a dual boot and the modem was originally installed in DOS for DOS only. We have tested this with mixed results. It seems to depend if OS/2 can configure the driver stably in memory. We have heard reports that the next version of OS/2, nicknamed Merlin, will support PnP. 4.2 Linux - How to setup a PnP modem Let the driver configure the modem on bootup by adding the DOS driver, device=F:\supra\dwcfgmg.sys, to config.sys before running Linux. This requires the use of LOADLIN to load Linux instead of LILO however. 4.3 Windows NT - How to setup a PnP modem There are two possibilities. 1) The BIOS automatically detects and configures the modem. If it configures the modem without a conflict, you are set. See 3.2 for information regarding the BIOS configuring the modem. 2) Dual-boot into DOS and have the DOS PnP software loaded. Once the modem is configured, warm boot into NT. It is important to not reset or cold boot as the modem configuration will be lost. Use Cnrl-Alt-Del to reboot. This will work in most cases but not all. 5 ICU 5.1 About the ICU The ICU is a utility which will allow you to modify a PnP card's resources. It is designed for DOS and Windows 3.1x. DO NOT USE WITH WINDOWS 95. Complete instructions for the use of the ICU are found in the ICU Users Guide which gets installed in the Supra program group in Windows. Please read the section regarding modifying a card card configuration. The ICU will only work if the PnP software is installed properly. 5.2 Changes made to in ICU or WinICU do not "take" Reason: The BIOS does not allow modification to its ESCD.RF file. This is likely only to happen on a few PnP BIOS'd machine. Solution: None. 6 Bios Compatibility Issues 6.1 Legacy install with Phoenix 4.04 BIOS 1. In the install.dat file on the PnP Utility Disk, there is a line which says at the end of the line "force partial install". Edit the install.dat file and at the start of the line which reads "force partial install", add "//" (minus the quotes). Rerun the install. It will prompt as though it is doing a partial install but will actually do a full install. 2. During the process if the installation, one of the most important files, the ESCD.RF file gets deleted when the install is working with this BIOS. Go to the \supra\icu directory and undelete that file. To do this type "cd \supra\icu" (minus the quotes), and press enter and then type "undelete" (minus the quotes) and press enter. When the undelete process prompts to undelete the file "?SCD.RF", press "Y" to undelete and when it prompts for the first letter, type "E". 3. Finally, the ESCD.RF file needs to be copied to the root directory. To copy the file type "copy escd.rf c:\" (minus the quotes) and press enter. Reboot the computer and the modem should be detected and configure properly. 6.2 Award 4.50PG w/1.0 Extension See 3.2 for NVS error and solution. 7 Software Issues 7.1 America Online Recommended init strings Init Strings: 1)AT&F2S95=1^M - generally works 2)AT&F2S95=1\N5^M - works even more often 3)AT&F2S95=1\N5*H-C1-K2- works only with modems which have MNP10 support (SupraFaxModems). Will not necessarily work but will work in some cases where the other init strings do not. 7.2 Comit for Windows 7.2.1 Not able to maintain connections or getting lots of errors Reason: Some copies of Comit for Windows did not have an &F2 in the init string for some 288i modems. Solution: Add an additional modem init string of AT&F2 and all should be well. 7.3 Doom 7.3.1 Not finding PnP modem Reason: Modem using upper IRQs Solution: Doom will not work at all with the IRQ of the modem set higher than IRQ7. If it is higher than that then the system locks up to the point where Ctl+Alt+Del won't work. This seemed to work in Win95 from a DOS Window and MSDOS 6.22. Cutting to the chase, Doom works with non-standard IRQ's but not Extended IRQ's.
