| + | ====== 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. | ||
