INIT0100: Format of device description information
Here are the outlines about formats for creating or changing the device used for a Telnet session.
The following table shows the format of the device description information, which describes the characteristics of the device to be associated with this session.
| Offset dec | Offset hex | Type | Field |
|---|---|---|---|
| 0 | 0 | CHAR(10) | Device name |
| 10 | A | CHAR(8) | Device format |
| 18 | 12 | CHAR(2) | Reserved |
| 20 | 14 | BINARY(4) | Offset to device attributes structure |
| 24 | 18 | BINARY(4) | Length of device attributes structure |
| 28 | 1C | CHAR(*) | Device attributes structure |
Device description information field descriptions
- Device name
- The specific virtual device to be associated with this Telnet session. For DISPLAY devices, if the QAUTOVRT auto-create device system value allows for it, the device is auto-created by the system if it does not already exist, and varied on. For PRINT devices, the system auto-creates the device if it does not already exist. If the exit program supplies no value, the Telnet server returns to the default of using the traditional Telnet virtual device selection methods. This should be a valid DISPLAY or PRINT device description name and must adhere to standard IBM® i object-naming conventions.
- Device format
- The specific virtual device type that is associated with this Telnet session.
Currently only display devices that the system supports.
- DSPD0100
- The device is a display. The system returns display attributes.
- Reserved
- Reserved for future use.
- Offset to device attributes structure
- The offset from the start of the device description information to the start of the device attributes structure.
- Length of device attributes structure
- The length in the user space of the device attributes structure.
- INIT0100: Format of display device description information (DSPD0100)
- The following table shows the format of the display device description information, which describes the characteristics of the device to be associated with this session.
| Offset dec | Offset hex | Type | Field |
|---|---|---|---|
| 0 | 0 | CHAR(3) | Keyboard identifier |
| 3 | 3 | CHAR(1) | Reserved |
| 4 | 4 | BINARY(4) | Code page |
| 8 | 8 | BINARY(4) | Character set |
DSPD0100 field descriptions
- Character set
- The character set that the system uses for this interactive job. You can find valid values in national language support (NLS). This field is identical to the Character set parameter of the Open Virtual Terminal Path (QTVOPNVT) API.
- Code page
- The code page that the system uses for this interactive job. You can find valid values in NLS. This field is identical to the Code page parameter of the Open Virtual Terminal Path (QTVOPNVT) API.
- Keyboard identifier
- The 3-character keyboard identifier that the system uses for this interactive job. The keyboard identifier implicitly specifies the code page and character set to be used, unless it is overridden as part of the Code page and Character set parameters. You can find valid identifiers in NLS. This field is identical to the keyboard Language type parameter of the Open Virtual Terminal Path (QTVOPNVT) API.
- Reserved
- Reserved for future use.
