None! You have to call directly into the OS socket API to setup a raw network socket and then use read() and write() on it. Note that raw sockets are under all modern desktop OSes privileged resources...

You could also use some sort of USB enabled device - like arduino or some FTDI USB chipas you want. I did such a device with an atxmega controller for a machine which gives some simple IOthat i use...

View ArticleRe: How to implement ethernet communication without TCP or UDP?
VISA doesn't implement access to raw ethernet sockets either but only TCP/IP. Would be also not practical as on all desktop systems raw sockets are only accessible from privileged processes. The way I...
