Hi,
I want to have a web service which reads data continuosly from an external hardware(eg rpm) on a serial port and returns a byte array.
I want to access this data from a aspx file. The problem is that since it is continuous data, i have to call the web service in a loop.. and this creates 100% cpu load.
Is there a better way to do it ?. I heard that there is pushlet technology in java where the server contiuosly sends data to the client (Javascript).. is there an equivalent in .net ?
In summary is there any way that the server could send data to the client continuosly without the client requesting for the data in a loop?
Thanks for any help.
