In your RPG you are only allowing one Socked Descriptor.  You must close the
SD between accepts.  If you program already has one connection, it will
refuse the second.  If you accept one connection and not close it properly,
you will have a lingering SD that you can not reuse.  I found it best to
delete the SD after closing then creating a new one to use.  It also looks
like you change SD upon accepting the connection, can the client do that?  I
don't know the C stuff to be sure?

Hello all,

I am attempting to socket from a win95 pc to an as400. Both systems are on
the same local ethernet lan. Both behind the firewall.
When I run connect( ) on the pc, a "WSAECONNREFUSED" ( the attempt to
connect was forcefully rejected ) error code is returned.

My "Listen" pgm is running on the as400.  It was able to rcv data on a
loopback test, so I am reasonably sure it is coded correctly.
** Create the socket.                                                
 C                   Eval      SD = Socket (AF_INET: SOCK_STREAM: 0 )
** Bind - set local address for the socket.
 C                   Eval      SocketAddr = *ALLX'00'
 C                   Eval      SinFamily  = AF_INET
 C                   Eval      SinPort    = 3005
 C                   Eval      SinAddr    = INADDR_ANY
 C                   Eval      rc = Bind (SD: %ADDR(SocketAddr)
 C                                          : %SIZE(SocketAddr))
** Listen - Invite incoming connections.
 C                   Eval      rc = Listen (SD: 1)<<<<<<<<< only 1 allowed
 ** Accept - Wait for connection request and Make connection.
 **   Accept incoming connection request from the client.
 **   A new socket (SD2) is created for the client.
 c                   Eval      SD2 = Accept( SD:
 c                                           %Addr(AccpAddr):
 c                                           %Addr(AccpAddrLgth) )
