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.

 Start REGEDT32.EXE and locate the following Registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\Serial\Parameters

  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:

     Serial3 ---     DosDevices : REG_SZ : COM3 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x100 PortIndex : REG_DWORD : 0x1

Serial4 ---     DosDevices : REG_SZ : COM4 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x108 PortIndex : REG_DWORD : 0x2

Serial6 ---     DosDevices : REG_SZ : COM6 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x118 PortIndex : REG_DWORD : 0x4

Serial7 ---     DosDevices : REG_SZ : COM7 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x120 PortIndex : REG_DWORD : 0x5

Serial8 ---     DosDevices : REG_SZ : COM8 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x128 PortIndex : REG_DWORD : 0x6

Serial9 ---     DosDevices : REG_SZ : COM9 ForceFifoEnable : REG_DWORD : 0x1 Indexed: REG_DWORD : 0x1 Interrupt : REG_DWORD : 0x5 InterruptStatus : REG_DWORD : 0x140 PortAddress : REG_DWORD : 0x130 PortIndex : REG_DWORD : 0x7

Quit Windows NT and turn off your computer. Restart your computer and Windows NT.</li></ol>

COM1 through COM9 can be directly referenced just like a filename from programs and from the command line. However, COM10 must be referenced with the following syntax:

<pre class="fixed_text">  \\.\COM10

NOTE: The command line MODE command does not recognize ports above COM9.
