Irc Client Agreement

Once the connection is established, the two clients exchange the completed CRLF messages. Messages starting with ASCII 001 (and ending as an option) will be interpreted as special commands. The ACTION command represents an emoticte, while others have lines drawn on the user`s whiteboard interface or allow both clients to negotiate a number of features. If the sending client supports DCC RESUME, it responds with: Client-to-client log (CTCP) is a specific type of communication between Internet Relay Chat (IRC) clients. The data is sent in blocks to the client, which the client must confirm by sending the total number of bytes received as a 32-bit network byte sequence. This slows down connections and is redundant due to TCP. The Send-Ahead extension relieves this problem a bit by not waiting for confirmations, but since the recipient still has to send them for each block received, if the sender waits for them, it will not be completely solved. An example of a CTCP-PING request for vom XChat client is as follows: ircII was the first IRC client, 1] The CTCP protocol was implemented in 1990 by Michael Sandrof for ircII version 2.1,[2], while the DCC protocol was implemented by Troy Rollo in 1991 for version 2.1.2. [3] CTCP is a common protocol implemented by most of the major IRC clients used today. [Citation required] CTCP expands the original IRC protocol by allowing users to view other clients or channels, so all clients on the channel respond to the CTCP according to certain information. In addition, the CTCP can be used to encode messages that the un formatted IRC protocol would not send through the link, for example.B. Messages that contain upheaval or the byte 0 (NULL) value.

CTCP does not establish a direct link between clients; However, it is often used to negotiate DCC compounds. A CTCP-PING requirement determines the ping rate that exists directly between two clients (for example. B discount on the server). The CTCP PING command sends an (often) integer argument (a timestamp) to a target client, the target client then responds by giving exactly the same numeric parameter. . . .
