From: mauro Gaggero on 22 Feb 2010 09:51 Dear all, I have to connect to a remote application via telnet (or netcat). So I use the command > telnet ip port from a command prompt. Later I send some commands via telnet to the remote application (the command made up by the string "I"). The application answers me with a sequence of bytes representing an image. My problem is: how can I import such a sequence on matlab in real time so that I can see the image? I would like to be able to send the command I directly in Matlab and pass the results directly to matlab... Any idea? Thanks in advance. Mauro

If your telnet program doesn't support this, you could try using an ssh client, (like putty) and connect over the telnet protocol. I think the result will be returned as a string, which you may need to parse using e.g str2num. |
