Parallel port access via web
« on: November 12, 2012, 05:04:21 pm »
Hi All:
I know how acces parallel port thanks to Jan Axelson´s book (by the way, the user with this name, here in this forum will the author of this book?), but now, I have a little question and I want to do it.   Can I access a LED with the parallel port via internet?
I have reas many articles but most of the are dor Linux? I want to do this with Windows XP o Windows 7.
Thanks in advance.

Here is one example of how to send and receive messages over a network using TCP/IP:

One computer can send a message to turn the LED on or off. When the PC with the parallel port receives a message, it can use an inpout DLL to toggle a bit on the parallel port.
