Hello, I work with an application in the Healthcare Industry that acts as a HUB for all of the different transactions generated by the Hospital. The app establishes TCP/IP protocol connections with various applications and all of the TCP/IP rules are handled under the covers. I am connecting to one homegrown Windows app that is having problems recognizing when my app shuts down the TCP/IP connection. Usually when this happens the other app release there port and indicates the connection is shutdown. This app I am working with will not acknowledge the shutdown and therefore my app cannot reconnect because the port is still busy. The questions, what usually would be sent out when I shutdown the connection? is this a sighup or something else? Would this be a standard TCP/IP signal that is sent? My application sits on AIX and like I said this stuff just happens, it is not documented to that level what ocurrs on the tcp/ip level. My guess is the other guy doesn't know much about TCP/IP and hasn't coded properly. (Not that I know anything better)

Thanks
