10.16 User-programmable serial interface
This chapter describes how to address the serial interface of the controller
from within the application program to allow sending and receiving characters.
The user-programmable serial interface lets you connect devices which use
communication protocols that are not supported by the OS of the controller,
Fields of application, for example, are:
 Scales

Scanners
 Display elements
 Frequency inverters

Temperature controllers
 etc.
This chapter addresses programmers of application programs with experience
in data transfer via asynchronuous serial interfaces. Expertise in the following
areas is prerequisite:
 Wiring of serial interfaces

Communication parameters (baud rate, parity, etc.)
 Transmit and receive buffers
 etc.
