Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
The following graph depicts the usage of the copy block.

But when the block receives the msg of '''pmt.from_bool(False)''' after 2.5 seconds, it starts dropping all of the upcoming data.

This block has an "enabled" message port that can be used to turn it on or off.

Message Ports

en
The 'Enabled' parameter of this block can be changed by sending a message at this port. Sending a Message PMT of pmt.from_bool(False) to this port via Message Strobe can disable the block. pmt.from_bool(True) can enable the block.

Initially, copy is enabled, so the data is transferred to the output of the copy block.
