The shared memory is managed by a very simple handskake protocol and seems to work well. It all seems stable and responsive and still only a few % CPU. This really now paves the way to plug in other stream managers for Jack and HPSDR and other controllers (I should have a Softrock in my Christmas stocking). I think this will now depart from the trodden path on Linux as I will ditch the pipes. Being a separate process anyway it seems pointless making it two processes.

Hi Bob,

Wow, this is great news.  I can't wait to get back into the software
part of the project and take a detailed look at erlink-sr.
