HS/Link is a file transfer protocol developed by Samuel H. Smith in 1991-1992. HS/Link is a high speed, full streaming, bidirectional, batch file transfer protocol with advanced Full-Streaming-Error-Correction. Each side of the link is allowed to provide a list of files to be sent. Files will be sent in both directions until both sides of the link are satisfied. HS/Link is also a very fast protocol for normal downloading and uploading, incorporating some new ideas (such as Full-Streaming-Error-Correction and Dynamic-Code-Substitution) to improve speed and provide greater reliability. HS/Link operates at or very near peak efficiency, often reaching 98% or more with pre-compressed files and non-buffered modems. Even higher speeds are possible with buffered or error correcting modems. A number of features, such as 32bit CRC protection, Full-Streaming-Error-Recovery and Dynamic-Code-Substitution, contribute to performance and security. HS/Link can resume an aborted transfer, verifying all existing data blocks to insure the resumed file completely matches the file being transmitted. This function can also update a file that has only a small number of changed, added, or deleted blocks. An additional feature allowed both remote and local user to chat depending on the file transfer bandwidth(s). ==External links== * (Samuel H.
