Authorization

Privilege Class: B

Purpose

Use this SET RDEVICE command to tell CP that line adapters or communication controllers are at specific device addresses.

Operands

rdev
rdev1-rdev2
specifies one or more real device numbers to be defined or changed. Each rdev specified must be a hexadecimal number between X'0000' and X'FFFF'. The maximum number of devices allowed within a range is 256.
EQid eqid
assigns the device equivalency ID (EQID) eqid to the RDEV. The eqid is a string of 1–8 alphanumeric characters. Note that for this device class, the specified EQID must be unique across all devices on the system.
NOEQid
removes a previously assigned EQID from this RDEV. After the device is varied online, it reverts back to a system-generated EQID.
TYpe
specifies the type of device.
BSC_ADAPTer
specifies an IBM Binary Synchronous Terminal Control Type II for a 3745.

The BSCA adapter is supported as dedicated-only.

IBM1_ADAPTer
specifies that an IBM Terminal Adapter Type I attaches a 1050 or 2741 to a 3745.
TELE2_ADAPTer
specifies that a CPT-TWX (Models 33/35) Terminal, 3101, 3151, 3161, 3162, or 3163, attaches to a Line Interface Base Type I in a 3745.
SET_ADDRess n
is the set address (SAD) command to be entered for a telecommunication line attached to a control unit. The default is 4.
The values for n and the corresponding commands are:
0
SADZERO
1
SADONE
2
SADTWO
3
SADTHREE
4
(No SAD command is entered)
3705
defines the base address that loads the 3745 communications controller.

Usage Notes

  1. When setting an EQID for a device of this class, the specified EQID must be unique across all devices in the system. If the specified EQID already exists, you will receive message HCP048E and the RDEV will not be created.
  2. The system cannot generate EQIDs for devices that do not support RCD CCW.

Examples

Example 1:

To specify an IBM Terminal Adapter Type 1 at device number 01F0, enter the following SET RDEVICE command: 
set rdevice 01F0 type ibm1_adapter

Example 2:

To specify three Binary Synchronous Terminal Control Type II adapters at device numbers 01F1, 01F2, and 01F3, enter this SET RDEVICE command: 
set rdevice 01F1-01F3 type bsc_adapter

Example 3:

To specify Binary Synchronous Terminal Control Type II adapters at device number 01F1 with an EQID of ABCDEFGH, enter this SET RDEVICE command: 
set rdevice 01F1 eqid ABCDEFGH type bsc_adapter

Example 4:

To specify Binary Synchronous Terminal Control Type II adapters at device number 01F1 and remove any previously defined EQID, enter this SET RDEVICE command: 
set rdevice 01F1 noeqid type bsc_adapter

Responses

After CP has issued a message for each device address affected by a SET RDEVICE command, the following summary response is displayed: 
xxx RDEV(s) specified; yyy RDEV(s) changed; zzz RDEV(s) created
