The following functions are part of input processing on the DP
EPS.
For online printing, the LCDS data is transmitted from a host
computer either directly or through a protocol converter. The DP
EPS receive print data either over a channel through bus and tag
cables, or through the Socket Gateway or lpr using TCP/IP
protocol.
The LCDS data stream emulates the IBM 3211 or 4245 line
printer format. All commands coded for the 3211 may be coded
for the 4245. In online 3211 mode, the data stream emulates an
IBM 3211 line printer format, with or without embedded DJDEs.
Basic input processing functions are augmented by the following
functions for online 3211 or 4245 mode operations:
• Handling all interactions with the online interface hardware.
• Building translate tables based on the present contents of the
current FOLD or UNFOLD command that is in effect.
• Processing form control buffers (FCBs) that are received from
the host to redefine channel to line number assignments.
Online printing is controlled through parameters from a user
defined .JDL file. You can dynamically override these parameters
by Dynamic Job Descriptor Entries (DJDEs).
The DJDEs that you specify are processed by the system as part
of the input print data from the host. The IDEN command
enables the system to identify DJDEs as commands and not part
of the input data. (Refer to the IDEN command description for
information on the use and parameters of this command.)
Nonprint files, such as font files, can be downloaded from the
host using the FILE command (refer to "FILE DJDE," in the
"DJDEs" chapter of this guide.)
