Software Utilities: DLL for Visual Basic access to ARCNET

Normally, Contemporary Controls Null Stack drivers interface to Visual C/C++ 32-bit applications. However, this DLL allows Visual Basic 6.0 applications running on Windows^® 95/98/ME/2K/XP to communicate through ARCNET NIMs that use COM20020/22 ARCNET controllers.

All COM20020/22 functions and data rates are supported except for event-driven mode.

Two sample applications are also provided — each demonstrating how to access the ARCNET controller.

• The “Talk” application allows two stations to exchange simple ASCII messages.
• The “WinLoop” application establishes a continuous communications “echo” between two stations.

Equipment Requirements:

• The card in the host computer must use a COM20020 or COM20022 ARCNET controller chip.

The online utility is in a self-extracting zip file which contains:

• the DLL
• the "Talk" sample application with supporting files
• the "WinLoop" sample application with supporting files
