Usage: DCC CHAT NICK [-encrypt <password>]
  DCC CHAT initiates a direct client connection chat to the given
  nick, who must respond with DCC CHAT. This is the most secure
  form of communication available on IRC. Messages sent via a DCC
  CHAT connection are not sent through IRC, but are sent by a direct
  connection between your client and the remote client. Messages
  are sent over a DCC CHAT connection with /MSG =nick
  You can also send CTCP messages (ie DCC SEND commands) over an
  already open DCC CHAT connection.

  DCC CHAT also supports ircII's internal encryption.  You can use
  it by doing:
    DCC CHAT nick -encrypt password
  Of course, the person you are chatting with must also be using a
  client capable of encryption, and must specify the same password.
