Fusion Embedded™ POP3Post Office Protocol version 3
The Fusion Embedded™ POP client package provides, via API functions, a complete implementation of RFC1939 “Post Office Protocol - Version 3”. Security is implemented via Fusion Net’s MD5 (RFC 1321) capabilities. Callback functions can be registered for each phase of the conversation between the server and the client. This allows the programmer visibility into the workings of the protocol and assists in debugging. The Fusion Embedded POP3 client simplifies access to email. Instead of just providing the commands spelled out in RFC1939 the interface in has been partitioned into logical blocks. Each block may make use of multiple RFC commands.
Fusion Embedded POP3 can run over both IPv4 and the next-generation Internet protocol, IPv6.
Fusion Embedded POP3 can run on Unicoi’s Fusion TCP/IP stack or on any TCP/IP stack with a BSD 4.4 compatible Sockets API.
The Fusion Embedded POP3 client provides the necessary tools to retrieve electronic mail from a POP3 mail server. This is done using TCP/IP to provide reliable delivery of data between the POP3 client and server. All communication is performed on a single socket. The POP3 client issues plain text commands to the server and listens for the plain text responses.
