Description
The input/output device type
Valid settings of IODEV are:
| IODEV | Access method/device type |
|---|---|
| 1 | CCAIN/CCAPRINT (User 0 only) |
| 3 | BSAM |
| 7 | SNA Communications Server 3270 |
| 11 | Remote User Language thread (full screen) |
| 19 | VTAM or TCP/IP (Horizon SQL thread) |
| 23 | Host Language IFAM thread |
| 25 | FUSI thread, new in version 7.6 of Model 204. These are created implicitly; as many threads are created as is the value of the FUNTSKN parameter. There is no reason to attempt to define these threads explicitly, although there may be, in future versions of Model 204. |
| 27 | VTAM (Horizon thread) |
| 29 | Remote User Language thread (line-at-a-time) |
| 37 | SNA Communications Server 3767 and NTO (z/OS)
Note: Value 37 is no longer supported as of Model 204 version 7.7. |
| 39 | IUCV User Language thread (line-at-a-time) |
| 41 | IUCV User Language thread (full screen) |
| 43 | IUCV Host Language Interface thread |
| 45 | CMS line-at-a-time console. This z/VM device setting is an ALTIODEV value; is cannot be specified on the user's parameter line. |
| 47 | CMS full screen console. This z/VM device setting is an ALTIODEV value; is cannot be specified on the user's parameter line. |
| 49 | VTAM or TCP/IP Horizon Remote Command Line (RCL) thread. |
| 51 | SNA Communications Server (Parallel Query Option/204 thread) |
Note: In addition to the above table of valid settings of the IODEV parameter, the value of IODEV on some Model 204 threads can be set as a result of other parameters:
Parameter Recommended Meaning SDAEMDEV 15 IODEV number for Sdaemons TNDEV 21 IODEV number for TNSERV threads
