Dials/LPFKeys location codes
For a Dials/LPFKeys device attached to a graphics input adapter,
the location code format is AA-BB-CC.
The individual fields are interpreted as follows:
| Item | Description |
|---|---|
| AA | A value of 00 for the AA field
indicates the controlling adapter card is located in the CPU drawer or system
unit, depending on the type of system. |
| BB | The BB field identifies the I/O bus and slot
containing the card. The first digit identifies the I/O bus. It is 0 for
the standard I/O bus and 1 for the optional I/O bus. The
second digit is the slot on the indicated I/O bus that contains the card. |
| CC | The CC field indicates the card connector where
the device is attached. The value is either 01 or 02,
depending on whether the attached device is port 1 or port 2 on
the card. |
Note: Serially-attached Dials/LPFKeys devices do not indicate location codes.
This is because these devices are considered to be attached to a tty device.
The tty device is specified by the user during Dials/LPFKeys definition.
