8. Programming ida FS 250 - non-IPDS
The ida FS 250 works using a large number of internal Setup Functions (FSL
Functions). FSL setup functions can be sent either from your IBM system or
from a PC.
When the protocol converter has been installed and connected to a printer,
you may have to consider the use of these setup options.
The factory default setup will meet the demands of most host systems and
users, and special programming is therefore normally not required.
However, special circumstances may require changes in the pro gramming of
the box. For full details on this please see the "5250 Programmer's Guide;
D62079". In the Programmer's Guide you will find an extensive description of
the FSL Functions with notes, comments and examples.
NOTE:
This section is a brief description of how to set up the interface with FSL
functions from the line. The section is primarily aimed at users who are
already familiar with i-data products.
8.1 The Escape Character
No escape character is defined when you receive the ida FS 250 from the
factory. When you send FSL Functions via the data stream, the functions
must be "separated" from the data stream, so that they are not printed. For
this you need to define an Escape (ESC) Character.
The ESC Character tells the interface that the characters following the ESC
Character in the data stream are to be regarded as a command. The
command string must also end with the ESC Character .
Before you define the ESC Character please note the following:
• Once the ESC character has been defined, it cannot be printed. For
this reason you must select a character which will not normally appear
in the data stream. If the character defined appears elsewhere in the
data stream (i.e. outside an FSL Function), the interface will regard it
as an ESC character and you will get a syntax error.
• However, you need not have an ESC Character defined all the
time. When it has served its purpose you can remove it again.
