Introduction Comment: If you are using only the UNIX system for Intelligent Ports Card operation, you can skip this chapter and go to Chapter 3, “UNIX System Device Driver Installation.” If you plan to use MS-DOS under Simul-Task 386, follow the procedures in Chapter 3. The instructions in this chapter apply only to native MS-DOS. See the secti ...
Installation Procedure The following steps define the sequence of events for installing the IPC-1600 for use in the native MS-DOS environment. Read the entire procedure and supporting paragraphs before doing the installation. Write down the hardware parameter settings for each board to be installed as you read through the procedure the first time. ...
Installation Procedure Preconfigure the IPC-1600 Boards Set the starting controller memory address (DS1, SW8—1), the I/O address (DS1, SW11—9), and the IRQ level (DS2, SW8—1) for each IPC-1600 to be installed. Note that IRQ levels are not used by the MS-DOS driver. Therefore all DS2 switches should be set to the OFF position (Note 2). Refer t ...
Installation Procedure Install the Hardware Refer to Chapter 4, “Hardware Installation,” and follow the instructions for the installation of the board. Ignore any instructions in Chapter 4 involving the DS1 and DS2 DIP switches, since they have already been done in this procedure. Load the Software Power up the system [AT&T Work Group Syste ...
Installation Procedure Now, change directory (cd) to IPC and copy the files on the diskette in the “A” drive or in the “B” drive to the system disk drive as follows. The example uses the “A” diskette drive; the system disk is the “C” drive. Change directory to an optional separate directory to contain the IPC-1600 software. C: $ cd ...
Installation Procedure Create or Modify the CONFIG.SYS File Use an editor, such as EDLIN, to change (or create) the CONFIG.SYS file in the root directory of the drive from which you boot MS-DOS. Add the following line to the CONFIG.SYS file if the IPC16DOS.SYS file is in a separate directory. The complete path name must be specified for the DEVICE ...
Installation Procedure Execute IPC16CNF to Configure the Driver The IPC16CNF.EXE program is used to configure or reconfigured the IPC-1600 MS-DOS driver and to specify individual channel (port) parameters.

Removing the MS-DOS Device Driver To remove the Intelligent Ports Card MS-DOS device driver from the system, use an editor, such as EDLIN, to delete the entry in the CONFIG.SYS file which corresponds to DEVICE=IPCIPC16DOC.SYS. Then reboot the system. If you want to free the system disk space occupied by the IPC-1600 software, delete (DEL) the IPC ...
Removing the MS-DOS Device Driver The following screen display shows how to remove only IPC-1600 driver and configuration software files from the system disk. The IPC16DIA diagnostic program remains on the system disk. C: $ del ipcipc16dos.sy s C: $ del ipcipc16conf.ex e C: $ After editing the CONFIG.SYS file, reboot the system to reconfigure ...
Limitations of the IPC-1600 MS-DOS Device Driver All IPC-1600 boards in the system must be assigned the same starting controller memory address; otherwise, only one board can be accessed under native MS-DOS. All IPC-1600s can be diagnosed regardless of controller memory address assignments; however, the controller memory address switch settings mus ...
