FTP is a protocol designed to enable reliable transfer of files over a network. The FTP protocol has been implemented using TCP (Transmission Control Protocol). µC/FTPc is a FTP client and it implements part of the following RFCs:
RFC 959: ftp://ftp.rfc-editor.org/in-notes/rfc959.txt
RFC 2389: ftp://ftp.rfc-editor.org/in-notes/rfc2389.txt
Draft IETF: http://tools.ietf.org/html/draft-ietf-ftpext-mlst-16
This document describes how to configure and use the µC/FTPc module in a µC/TCP-IP, µC/FS, and µC/OS-II or µC/OS-III environment.
