6500-LU3-DSE-Local SNA 3174 Control Unit

LU3-DSE mode is utilized when no host printing controls are required to accomplish the print function desired. The printer settings will be used and cannot be overridden by the host system. An existing local 3174 SNA-connected control unit is assumed. The steps required to install an LU1-DSE printer for host definitions are as follows:
  1. Define to VTAM by adding logmode entry to VTAM Logmode Table
  2. Define to JES2 (Not required but recommended. See details below)
  3. Define to CICS or another Application Program such as VPS or JES328X products.
  4. Select the options on the printer that are appropriate for the environment.

Step 1 - VTAM Definition

The following should be added to the Local Major Node VTAM definition. The printer will be attached as an LU1-IPDS capable printer.

LOC3174 VBUILD   TYPE=LOCAL

LOCPU74 PU       CUADDR=nnn...

LOC6500 LU

LOCADDR=n,MODETAB=MYMODETB,DLOGMODE=printer,ISTATUS=ACTIVE

The following entry should be placed in the VTAM MODE TABLE specified above or another of your choice.

6500DSEL MODEENT LOGMODE=6500DSEL,

         FMPROF=X'03',TSPROF=X'03',PRIPROT=X'B1',

         SECPROT=X'20',COMPROT=X'3080',RUSIZES=X'C7C7',

         PSERVIC=X'038000000000185018507F00'

         PSNDPAC=X'00',SRCVPAC=X'00',SSNDPAC=X'00'

Step 2 - JES2 Definition (SYS1.PARMLIB)

RMT1 LUTYPE3,BUFSIZE=3840,LINE=1,NUMRD=0,NUMPR=1,NOCOMP,NOCMPCT,

         SETUPHDR,CONSOLE

R1.PR1 CLASS=A,NOSEP,PRWIDTH=132,NOFCBLOD,WS=(W,R,Q,PMD,LIM,F,T/C,P),

         CKTPAGE=30

DESTID NAME=LOC6500,DEST=R1

Step 3 - Define to CICS or another application program

Refer to the vendor documentation for defining a DSE printer to the program for its use. Host system commands to change printer settings are not supported in DSE mode.

Step 4 - Printer Settings

It is recommended that the following printer settings be changed from factory default settings:

In LU3 mode the printer settings control the orientation, CPI, LPI and all other aspects of the printed output. Therefore, you must set the printer settings to match the characteristics of the job you are printing. Host controls are not supported in this mode.
