4 Controlling printer and serial
interfaces
This chapter describes how to control printer and serial interfaces from within the
application program of a controller.
Printer and serial interfaces can be controlled in 2 ways:
■ Direct access to registers of the interface
■ Using display functions included in the STX language set
The following table lists the printer and serial interfaces supported by the con-
troller. It also indicates the device number the display command needs to ad-
dress in order to output information to the interface.
