ControLink86 Realtime Networking Software
ControLink is composed of two parts, a host interface (referred to as the Class 1 Interface) and a low
level hardware interface. This architecture is illustrated by Figures 2 and 3. The host interface provides
the network interface to the host system. ControLink is based on a ‘mailbox’ type messaging service
where the Class 1 driver acts as the ‘postal service’. The Class 1 driver uses a logical address called a
Service Access Point, or a SAP, to address each mailbox. The system designer assigns the ‘mailbox’
addresses at initialization using ControLink commands.

2.1HOW TO USE CONTROLINK
ControLink86 is delivered as source code to be linked with the target application. Aside from the source
code there are additional files that provide auxiliary functions like declarations and definitions.
Two programming examples complete with the application code, make files (for Microsoft Visual C++)
and executables are included. The distribution diskette structure has the following structure:
