7–12 XEROX 4235 LPS INSTALLATION PLANNING GUIDE
OS/VS1
Environment description
In an SNA environment, the 4235 LPS emulates a 3777 Model
3 communication terminal. The 4235 LPS may be defined as a
remote job entry (RJE) terminal operating in any of the three
modes available: 2770, 2780, or 3780. As a remote terminal,
OS/VS1 and JES/RES facilities support the 4235 LPS.
Initialization process review
The 4235 LPS is defined to RES using standard RES system
generation statements. The five–step process requires only the
addition of several statements to the standard generation
procedure.
1. Review global parameters and specify values.
2. Specify remote terminal parameters (TERMINAL).
3. Specify line parameters (LINE).
4. Perform RES and RTAM generation defining the RES data sets,
SYS1.UADS, and SYS1.BROADCAST, and add logon
procedures to PROCLIB.
5. Add user IDs for 4235 LPS users.
System generation procedures
Step 1.
The following parameters in the RTAM macro are affected by
the 4235 LPS.
TPBUF
The number of teleprocessing buffers should be at least as large
as the number of teleprocessing lines.
TPBFSIZ
The recommended buffer size is 512; this value is used only
when operating in 2770 mode and can be larger if required for
other devices in the network.
NPR=YES Specifying YES allows interruption of printed output by the
central operator.
Step 2. Each 4235 LPS is described by a TERMINAL macro, specified
according to device type.
TERMINAL TDESCR=(5,n,3,n),PCHS=1,
(COMPRES=YES,BUFXSIZ=512,)PLGN=n,(LNUM=n)
