I am trying to use 100 (6060 ... 6160 port) port for listen. It is okey !
netstat -a I can see program listening port...
i am trying to connect from GPRS connection 0.0.0.0: 6100 , port . If i get connection with server PC and GPRS modem everything seems ok . But if close modem suddenly . My VB program still shows that prot connected to GPRS modem. IT doesn't recognize the ports down? It couldn't close port If ı want to close from program ( close all port ) ?
how can i close all port form my program ?
couldn't close port !!!
How can i understand remote GRPS closed ? ( because i can see port still connected to GPRS modem while i close my GPRS modem!!)
