AT&T IPC-1600 manual Number of Boards Option

Installation Procedure

Number of Boards Option

The N)umber of Brds option is used to specify the number of installed IPC-1600 boards. The default is seven boards. Once specified, the initial table is redrawn to show the number selected.

Memory Segment Option

The M)emory Segment option is used to specify the controller memory starting address for all IPC-1600 boards. When selected, the table is redrawn to show the new data. Remember that if all IPC-1600s are to be usable under native MS-DOS, all boards must have the same memory address. Select “8” to specify the default address 080000h.

The following screen display shows the available memory address options.

Driver Support Option

The D)river Support Option is used to specify DOS or INT 14 support. The default is DOS support. INT 14 support is provided for experienced users.

Selecting DOS support assigns and uses names for the individual communications ports so that they can be accessed from DOS and high level languages. The ports can also be accessed through INT 14h calls.

Selecting INT 14 support deactivates the DOS capability of assigning and using names for the installed communications ports. This allows the channels to be accessed only through INT 14h calls. If DOS support is not desired, selecting this option decreases the size of the driver.

The following screen display shows how to select these options.
