This article provides information on the different types of Digiboard adapters, on contacting Digiboard, and on the currently supported Digiboard adapters under Windows NT. The following section, Digiboard Adapter Support covers the different types of Digiboard adapters and the Microsoft product support boundaries for Digiboard problems. The next section, Digiboard Contact Information, covers all the ways you can obtain help or files from Digiboard. The last section, List of Supported Digiboard Adapters, covers the current list of adapters that Windows NT supports. Note: Some of the supported adapters require drivers from Digiboard; check the following section to see which do.


Digiboard manufactures two general classes of serial adapters: intelligent and non-intelligent. These products are installed and supported in two different ways under Windows NT.

Digiboard Non-Intelligent Serial Products




Support for the non-intelligent Digiboard is provided by the native Windows NT serial device driver. These adapters are treated as any other standard serial adapter.

Non-intelligent boards are configured by hand-editing values in the Registry. This is necessary to create some special entries required for the Digiboard adapter. Information on this procedure is available in section 19.0 of the README.WRI file located in SYSTEM32 sub-directory.

Primary Support:

Primary engineering support for this device driver is provided by Microsoft. Microsoft will assist you in editing the Registry and using the device with Windows NT applications. If you suspect your adapter is not configured correctly or is malfunctioning contact Digiboard.

Digiboard Intelligent Serial Products


2Port MCA

  • Version or later of the MC/Xem driver for MCA computers is required for full support of this adapter under Windows NT.


The Intelligent Digiboard adapters listed above require a custom device driver. Custom drivers are independently developed by Digiboard and are distributed by Microsoft with Windows NT. If you use any of the adapters above, contact Digiboard for driver updates.

You can install the Digiboard drivers from Control Panel in the Networks section. The supported Digiboard adapters are listed in the Add Adapter dialog box.

Primary Support:

Digiboard provides primary support for their custom device drivers. Similarly, for a malfunctioning adapter, contact Digiboard. Microsoft will provide support for network configuration issues such as setting up Remote Access Services.
