Guilty ;)

Never heard of gcp:// slight typo I assume...

We use kplex for testing.

http://www.stripydog.com/kplex/

 In order to simulate real world as near as possible we run kplex on 
one server - mine looks like this:

kplex serial:direction=in,filename=/dev/gps_data,baud=9600 
tcp:direction=out,mode=server,persist=no

This provides us with tcp feed as tcp://192.168.0.1:10110

Then we can simulate different types of disconnects either by unplugging 
cable or using iptables to block comms out of the server running kplex

Happy coding!!
