Special Settings
This chapter describes those FSL Functions specifically related to
the requirements of the IBM 3270 system. SCS command related
Functions, Functions which need to be stored and where powering
off and on the converter is needed to inform the controller about the
functionality, IBM RPQs and Intervention Required Timer (IRQ).
Some of the 3270 related functions are normally controlled from the
front panel on an IBM 3268/87 or an IBM 4214 printer. On the IBM
3287/3268/4214 printers, it is also possible to change the following
front panel settings via the line (in LU1 mode only).
Lines per inch (LPI): 3,4,6 or 8 LPI
Characters per inch (CPI): 10,12,15,16.7 CPI
Maximum Page Length (MPL)
Maximum Print Position (MPP)
The converter may be set up to emulate this control via the line on
your printer.
LPI can be selected either by Function Y2, LPI, or by the SCS
command SLD.
CPI can be selected either by Function Y3, CPI, or by the SCS
command SPD.
MPL can be selected either by Function Y5, Form Length or by the
SCS command SVF.
MPP can be selected either by Function Y6, Maximum Print Position
or the SCS command SHF.
The settings emulating the front panel settings on an IBM
3287/3268/4214 printer is the value stored in Function 2,3,5 and 6
which will be the actual value at power on.
The IBM 3270 datastream also comprises attributes which can be
used for selecting underscore, colour and APL.
For underscore selected by attribute, please refer to the FSL
(D62071), PCL (D62030) or XES (D62067) specific manuals as
