The pibstat command in the DM account displays the current PIB status bit settings for a specified value.
|value||A 2-byte PIB status returned by the where command, under the column labeled PIB Stat.|
The pibstat command is perhaps the most useful indication of resource use on a D3 machine. The first two digits of this value indicate the state of a process. Some of the more common values include:
|f3xx||Waiting-for-input or displaying text.|
|e3xx||Waiting-for-input or displaying text with echo off.|
|f5xx||Displaying text, but line is in xoff (CTRL+S) state.|
|ffxx||Process is currently using the CPU.|
|bfxx||Process is currently sleeping.|
|dfxx||PIB currently requesting disk I/O.|
Returns the PIB status for port 68 as ff10, which can then be used in the pibstat command:
