+====== Netzer Connections ======
+===== Connection data =====
+First you have to localize the Netzer within the network.
+You need to know either the IP address or the MDNS name.
+More you can find in the article [[start]].
+Furthermore we distinguish between different connection ports:
+^ Destination point ^ Standard port ^
+| Web pages | 80 |
+| [[gpioserver|GPIO server]], only project **[[io_project#io_base|IO_base]]** | 65000 |
+| [[serialserver|Net socket (serial server)]], only projects **[[io_project|IO]]** and **[[spislave_project|SPISlave]]** | 64000 |
+All standard ports can be changed at will.
+===== Connecting with terminal program =====
+Often only a serial connection should be tested or some GPIOs must be read.
+For that reason it is recommended to use a terminal software to connect to one of the Netzer destination points.
+==== Windows ====
+In WindowsXP there was the program HyperTerminal which could establish raw TCP/IP connections.
+{{:de:netzer:hyper_terminal.gif?nolink&|Starting view of HyperTerminal}}
+An HyperTerminal alternative is **[[http://www.chiark.greenend.org.uk/~sgtatham/putty|PUTTY]]**.
+Further variants you can find [[links#tools|here]].
+While using **[[http://com0com.sourceforge.net|com0com]]** and the included **com2tcp** you may use any terminal program.
+You do not have to use telnet or TCP/IP sockets.
+That is also more important if you have to transmit or receive binary data.
+com2com establishes a pair of virtual COM ports, which are connected internally.
+They are called CNCA0 and CNCB0 for example.
+Now you can connect your chosen terminal program with CNCA0.
+Sent characters are visible at CNCB0, characters sent on CNCB0 are received within the terminal program.
+With com2tcp you can connect CNCB0 via TCP/IP to Netzer.
+This [[http://com0com.sourceforge.net/doc/UsingCom0com.pdf|manual]] describes important details for installation and usage.
+=== Opening a connection with com2tcp ===
+  - Open command line (Start menu, run, type 'cmd')
+  - Type: <code>com2tcp --ignore-dsr \\.\CNCA0 ne2c3d9f.local 64000</code> Adjust for your Netzers name and port accordingly. Instead of the name you also can type the IP address.
