JC-120MC Programming
10.10 Controlling printer and serial interfaces
This chapter contains information on how to control printer and serial
interfaces from within the application program in a JC-120MC.
Printer and serial interfaces can be controlled in two ways:
 Direct access to registers of the interface

Using display functions included in the STX language
In order to output special or control characters or to retrieve the status of the
external device, direct access to the registers of the interface must be used.
For more information on how to access registers refer to the documentation on
the corresponding module.
This chapter describes how to control the interfaces using display functions. It
also describes the registers used to parameterize the display functions. The
controller provides the following display functions:
 Displaying texts
 Displaying the contents of variables
In this manual we proceed from the assumption that the user is familiar with
the following STX instructions:
DisplayText()
,
DisplayText2()
, and
DisplayValue() . For a more detailed description of the instructions
mentioned above refer to the online help included in the programming tool
JetSym.
