3270 printer and SLU 1 compatibility
To use the extended attributes of color, highlighting, and programmed symbols, or to use the set vertical format or set line density data streams, you might need to modify your application programs.
Additional 3270 printer devices attached to a non-SNA control unit compatible with the currently installed 3270 printer devices use the existing 3270P model 1 or model 2 device formats. For the printer buffer, they use the existing IMS system definition with 480 characters (current model 1) or 1920 characters (current model 2).
MFS users choosing to change device attachment to SLU 1 must change their MFS device format definitions as shown in the following table. The following table lists the current device, the MFS device type, new control units, system definitions, and MFS device types, and the z/OS® changes required.
| Current Device | Current MFS DEV TYPE | New Device or Control Unit | New IMS System Definition | New MFS DEV TYPE | z/OS Changes Required |
|---|---|---|---|---|---|
| 3284/3286 | 3270P | 3827/3289 attached to a 3274 or 3276 SNA control unit | SLUTYPE1 | SCS1 | See Note |
| Note:
Change DEV TYPE=(3270P,n) to DEV TYPE=SCS1 and recompile. Or, if all printers are not changed to the new device or control unit, add the following after DEV TYPE=3270P and recompile:
