Hallo zusammen,
ich möchte im Netzwerk eine Kommunikation zwischen 2 Rechnern ermöglichen.
Beide PC's sollen dabei sowohl Nachrichten empfangen alsauch senden können.
Ich hab mir dazu mal die TCP-Funktionen angesehen und diese etwas umgebaut.

Es scheint zu funktionieren, allerdings nur genau einmal 
Worin liegt mein Denkfehler?

P.S. Danke schonmal für die Antworten
