LINKUP 5294 WITH DL5294 FIRMWARE
138
Figure E-1 shows the Remote Configuration Setup, consisting of one point-to-point/leased line, two
display stations, and a matrix printer. The LinkUp 5294 emulates IBM Model 12 and/or IBM 5294
Cluster Controllers.
Signing on to the System/38 console with the Security Officer Password displays the command- entry
screen. The command-entry screen allows entry of System/38 Control Language commands to perform
functions of the system's Control Program Facility (CPF).
A sample Remote Workstation configuration is listed below:
1.Terminate Subsystem (QINTER)
2.Create Line Description
3.Create Control Unit Description
4.Create Device Description
5.Add Work Station Entries For Subsystem
6.Vary Communication Line On
7.Vary Control Unit On Line
8.Vary Devices On Line
9.Start Subsystem (QINTER)
STEP 1. Terminate Subsystem QINTER
Prior to terminating the subsystem QINTER, check that all workstations are signed off. Enter the
terminate subsystem command TRMSBS. Press the Command 4 key. Pressing this provides a prompt
screen for entering parameters for the TRMSBS command. The command example below cancels all
interactive jobs in the QINTER subsystem and terminates the subsystem.
::TRMSBS SBS (QINTER) OPTION(*CNTRLD) DELAY(60)
NOTE
In this example, we are using the subsystem QINTER, an interactive subsystem
supplied by IBM. Verify that this is the appropriate subsystem for creating or modifying
your system devices. Do not assume that QINTER is the only interactive subsystem. To
determine if other interactive subsystems exist, enter DSPSBS SBS(*ALL).
STEP 2. Create Line Description
Entering the Create Line Description Command CRTLIND (see below) creates a line description for the
specified communications line. The line command describes line features to the system; this includes the
description of the modem (and its features) connected to the line. In Figure E-l, the remote line consists
of a point-to-point/leased line with non-IBM modems attached. This line is configured as a Primary
Synchronous Data Link Control (SDLC) at 9600 baud rate with a 4-wire connection.
Many of the prompts in this example are not included in the command example below. If a value is not
included in the command statement the default value is assumed by the system. Before using this
command, you should refer to the IBM Guide To Product Installation and Device Configuration and the
IBM System/38 Control Language Reference Manual for considerations relating to communications
lines interfaces and to modem characteristics, types, and features.
::CTRLIND LIND (LINKUP1) LINNBR (20) TYPE (*SDLCP) CNN(*PP)+
RATE (9600) SELECT(*NO) NONRTZN(*YES) CLOCK (*NO) WIRE(4)+
OEMMDM(*YES) TEXT (POINT TO POINT LINKUP INE 1')
