# nmap -P0 -p80,99,113 scanme.nmap.org

As you can see above, Nmap starts by sending a SYN probe back to each
of the three ports.  Port 113 replies with the RA (RST/ACK) flags and
thus is listed by Nmap as closed.  Port 80 returns SA (SYN/ACK) and so
is listed as open.  Port 99 does not reply, so Nmap retransmits after
1.1 seconds.  There is still no reply, so Nmap lists the port as
filtered.
