Application Programming With
Communications Products
The major function of communications applications running on NonStop S-series
servers is to support the transfer of information between a NonStop S-series server
and other systems or between a NonStop S-series server and data-capture and
data-display devices.
This section discusses the interfaces and some general concepts related to writing
applications that use HP communications subsystems. The term application in this
section refers to the program you write to perform communications functions; the same
program may be part of many different business applications.
