Chaos SEND protocol

The Chaosnet SEND protocol is used to send short messages between users on a network.

A connection is established by the originator of the message by sending an RFC packet with the SEND contact name. After the contact name (and a space character), the recipient's user name should be specified.

Subsequent DAT packets contain the message contents, using the Lispm character set. E.g. newlines are encoded as 215 (octal).

The first line of the message should have the format "user@host timestamp", where "user" is the sender's user name, "host" is the sender host, and "timestamp" is a free-format time specification for the message.
