Hi all,
I am working on developing a OOT module. It is a source block which reads
the data from a virtual usb com port.
This block is connected to a file sink through a throttle block

Team Platypus ran into this precise problem at the DARPA Hackfest. The
only solution was to code it up ourselves. It's non-trivial, but not too

I am using the gr-eventstream package in GNUradio, and I need help with the
EventStream Source block. This is a block that takes a PDU as a message input

Hi Jim,

So, each time you run your flow graph, the following line should

Now, remove the ctrlport monitor from your flowgraph (disable it);
