This file contains information that was unavailable at the time that the manual went to publishing. It contains the following: 1. Installation instructions for Windows NT 4.0 2. Hints for installation with OS/2 -------------------------------------------------------- IBM ISA 33.6 Plug and Play Modem Windows NT Installation Please refer to your manual for information on selecting an open IO port and IRQ. Please note that since Windows NT 4.0 does not support "Plug and Play" operation, the modem must have its jumpers set prior to installation. Use one of the recommended jumper settings for the modem that are shown in your manual. Once the modem jumpers have been configured, you should install the modem in an open ISA slot and then turn on your NT computer (Workstation or Server). Once you are booted click on the START button then move to Settings and then Control Panel to load the Windows NT Control Panel. Once you have opened the Control Panel double click on the Modem icon. This will allow you to select the installation of a new modem. Note that it is recommended that if you have previous modems installed you should remove them all from the Control Panel Modem icon and start at the beginning of this document at the START button in the main screen. Just click on NEXT to begin modem detection. Once the detection finds the modem it will begin to query the modem looking for configuration information that could be identified in existing INF's in NT. If NT doesn't find any existing INF files with the modem information it is looking for, it will automatically select a "Standard Modem". At this point you need to select the CHANGE button. Now, you will need to select the HAVE DISK button. At this point you need to put your Support Diskette provided with the modem into your diskette drive and click on the OK button. The detection should see the INF on the disk, and you will get a screen showing the IBM 33.6 ISA Plug and Play Data/Fax Modem. Select IBM 33.6 ISA Plug and Play Data/Fax Modem and then click on the OK button. Now click the NEXT button, and you should receive a message from Windows NT that the modem has been set up successfully. At this point click on the FINISH button, which will then let you edit the Modem Properties. You may now exit this screen, and you are finished. -------------------------------------------------------- IBM ISA 33.6 Plug and Play Modem OS/2 Installation Hint In ALL versions of OS/2, when the modem is installed as COM3 or COM4, the CONFIG.SYS file needs to be modified. The serial communications driver, COM.SYS, is designed to support COM1 and COM2 with no modifications. In order for COM3 and COM4 to be used, you must modify the line in the OS/2 CONFIG.SYS file that reads: DEVICE=C:\OS2\BOOT\COM.SYS by adding a parameter. This parameter will consist of three items, separated by a comma. The three items are: a. COM port number b. Modem base I/O address c. Modem interrupt For COM3 and IRQ4, the statement would read: DEVICE=C:\OS2\BOOT\COM.SYS (3,3E8,4) For COM4 and IRQ5, the statement would read: DEVICE=C:\OS2\BOOT\COM.SYS (4,2E8,5) Note that the modification to COM.SYS must also be performed under WARP 4.0 PnP operation, if PnP assigns the modem to COM3 or COM4.
