8.39. DSPAUTO -- Enable Automatic DSPLOAD Status Messages
This command sets or queries whether or not DSPLOAD messages will be automatically generated whenever the
DSP utilization changes.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
Example Description Status Message
F01DSPAUTO1

8.40. DSPLOAD -- Query Percentage of Variable DSP Resources
Used
This command queries the current percentage used of the available variable DSP resources. When this number
reaches 100 percent, no more variable DSP veatures may ben enabled. An 'ERROR#060' will be generated if a
command attempts to exceend 100 percent utilization.
If the
DSPAUTO feature is enabled, then a DSPLOAD status message will be generated automatically any time the
percent utilization changes.
Example Description Status Message
