what is the best way to get live data from serial port and save it in SQL database? and display it on ASP.开发者_开发问答NET website ?

Is it something that can be done by webservices or client side programm is required to install on the machine ? any suggestions ?

You'll need two separate applications.

One to read the data from the serial port and send it to your web application via web services to be written to the database.

The second would the be actual web application including the web services to receive and write the data to the database as well as displaying the data on the site once it is uploaded.
