Main protocol stack

The main protocol stack for GS/TCP consists of a single executable "tcpip" which is installed in /usr/sbin under GNO. This executable forks itself into 5 separate GNO processes which handle various protocol levels and timing: Connection to GNO's PF_INET socket routines is made through a special kernel hook. Communication with network interfaces takes place through a combination of System 6.0.1 IPC messages and special call back functions.
