POP3 (Post Office Protocol version 3) is a protocol designed to allow smaller nodes in the Internet not able to maintain a message transport system to manage mail in a useful fashion. The POP3 protocol is used to allow a workstation to retrieve mail that the server is holding for it.
µC/POP3c is an add-on product to µC/TCP-IP that implements the client POP3 protocol. µC/POP3c implements part of the following RFCs:
RFC #1939 ftp://ftp.rfc-editor.org/in-notes/rfc1939.txt
RFC #2822 ftp://ftp.rfc-editor.org/in-notes/rfc2822.txt
This document describes how to configure and use the µC/POP3c module on top of µC/TCP-IP in a µC/OS-II environment. A Cogent CSB337 (ARM9) development platform with IAR compiler is used to demonstrate the typical application of this module, but other platforms and tool chains may be used as well.
