Make sure that the same port number is not being used
simultaneously by more than one process, including FTP services.
Sockets can remain in ESTABLISHED or some later status even if
closed; be sure to close ports from both sides of the connection.
A socket can remain open in TIME WAIT status for up to one minute
on the side that closes the socket first; we recommend that the
active-side port number be set to 0 and that you close the socket
from the active side. If you are using the Socket Service Request
Switches, check the response code to see if it is 0049 Hex.
