SUMMARY
=======
Adapter drivers for the non-intelligent Digiboard PC/8 adapters are not
available for Windows NT versions 3.1 and 3.5. The configuration for the adapter
is accomplished through the Windows NT Registry only. This article describes how
to configure and utilize the non-intelligent Digiboard PC/8 adapter in Windows
NT versions 3.1 and 3.5.
MORE INFORMATION
================
There are nine switch blocks on the Digiboard PC/8 adapter. Listed below are the
switch block settings of the adapter and Registry settings for each
communications port of the adapter.
Switch Block Settings
---------------------
Switch Block One (DS1) is used to configure the adapter's Interrupt Status
Register address.
Switches Description
--------------------------
Switches 1-7 Adapter I/O port address
Switches 8-9 Set these to the ON position
Switch 10 Enables (ON position) the Interrupt Status Register
The remaining eight switch blocks are used to configured the I/O port addresses
for each communications port of the adapter. Switch 8 on each of these blocks
enables (ON position) the port. The I/O port addresses available range from 000H
to 3F8H.
Registry Settings
-----------------
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
1. Start REGEDT32.EXE and locate the following Registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\Serial\Parameters
2. Listed below are entries that need to be manually added to be able to use the
ports on the Digiboard PC/8 adapter. To add a key for each entry, choose Add
Key from the Edit menu. Enter "Serial3" (without the quotation marks) for
COM3 on the entry for Key Name. Leave the Class entry blank, and then choose
OK.
To enter each value, choose Add Value from the Edit menu. Enter values of the
following:
