The MISC server sends a repetitive stream of character data without regard to its content. A TCP-based server listens for TCP connections on TCP port 19. When a connection is established, a stream of data is sent to the connecting application. Any data that is received is thrown away. A UDP-based server listens for UDP datagrams on port 19. When a datagram is received, an answering datagram is sent that contains a random number (between 0 and 512) of characters. The data in the received datagram is ignored.
The data that is generated follows an ordered sequence. It repeats a pattern of 94 printable ASCII characters in a ring, so that character number 0 follows character number 94.
The following example shows the repeated pattern.
