A link protocol that provides essentially an unlimited number of reliable connections between processes on two machines, where each end of the link can be either an Amiga or a Unix (BSD4.3) machine. Works on the Amiga with any EXEC device that looks like the serial.device. Works on UNIX with tty and socket devices. Achieves better than 95% average throughput on file transfers. This is version 2.0, an update to version 1.20 released on disk 145. Includes sources for both the Amiga and Unix versions. Author: Matt Dillon
