The TCP flags shows what the sending TCP entity wants the receiving TCP entity to do. In this case SYNchronize with the sender, using the other data listed. Check the TCP/IP Guide for details.

And be sure to have a look at the various TCP-related RFC's, such as the original TCP RFC, RFC 793, as well as RFC 3168, which introduced the ECE and CWR flags, and RFC 3540, which introduced the NS flag. These 3 latter flags are not [yet] mentioned in the TCP/IP Guide.
