UHD: avoiding AD9777 power-down

Hi folks,

I’m writing a basic C++ UHD app to control some custom hardware on the
USRP2/N. My hardware needs to continue sending out RF through the AD9777
DAC even after my host app closes. Problem is, UHD seems to tell the
AD9777 to enter sleep mode at this point; is there any way to alter this
default behaviour short of modifying the UHD source?

Another option would be disabling host-based modification of the AD9510
and AD9777 settings entirely; I’ve modified the ZPU firmware to
configure them upon boot-up anyway. I’d like to avoid this if possible
though.

Thanks in advance,

Vlad
