none There is no reply section just the STATUS section
stating the results of setting PGA N with opt[,val]
This is only available if PGA mining is enabled
If the PGA does not support any set options, it will
always return a WARN stating pgaset isn't supported
If opt=help it will return an INFO status with a
help message about the options available
The current options are:
MMQ opt=clock val=160 to 230 (and a multiple of 2)
When you enable, disable or restart a GPU or PGA, you will also get Thread messages
in the cgminer status window

Feature Changelog for external applications using the API:
API V1.22
API V1.23
Added API commands:
'pgaset' - with: MMQ opt=clock val=160 to 230 (and a multiple of 2)
----------
API V1.22 (cgminer v2.10.1)
Enforced output limitation:
all extra records beyond the output limit of the API (~64k) are ignored
