Hello, I'm trying to use the packages Network and Control.Monad.BinaryProtocol together, with a very simple program in which a client sends an operation to the server, which computes the result and sends it back. But the server holds when trying to receive (Server.hs, line 22), whereas the client has actually sent the data (Client.hs, line 17). The server stops to hold only when the client is killed with a Ctrl-C. This should be rather simple, and I can't get to know why it doesn't work. The files are here: http://old.nabble.com/file/p28157883/Client.hs Client.hs http://old.nabble.com/file/p28157883/Server.hs Server.hs http://old.nabble.com/file/p28157883/SharedData.hs SharedData.hs ----- Yves Parès Live long and prosper -- View this message in context: http://old.nabble.com/Simple-binary-protocol-through-network-test-tp28157883...
