DX-600/800
APR 2002
Edition 1.0
The client generates random sequential numbers initially and sends them to the server. The initial
sequential numbers are synchronized with the clock and increments the counter every 4 msec.
The Server responds with an acknowledgement that increments the initial sequential number by one. The
ACK bit number is also changed to a "1" value. The "SYN" can have and identical "ACK" response for each
packet, thus, the server and the client can establish a connection.
