Is there a status indicator in the USRP2 C++ interface that flags underflows? I am trying to push samples (using the std::complex<int16_t> type) to the USRP2 at an interpolation factor of 4. It seems to be working, but I require hard evidence that I am not underflowing.
The easiest way right now is to monitor the debug serial port. When there are underruns, it prints "U". Eventually, we'll have it reporting all the way back to the host, but haven't implemented that yet.
