Hi Martin, thanks for the reply. I dont want to build a TCP link per se. What I would like to do is to capture a network packet, like a sniffer does. After having the packet bit stream (as if it the bits were generated inside GNURadio), perform the signal processing over it with GNU Radio to `transmit`. At the receiver end I would like to recover the original packet bits and send it to an application.
If everything is fine I would capture a ping packet (from machine A to machine B), `transmit` it with GNU Radio. At machine B, I would recover the original ping packet and reply it. Pings are only an example, I could be any packet generate externally by another application.

I'm not sure where the code is, but there's videos of Balint playing networked games across a GNU Radio TCP link.
