Communication ports of which computer? The server? The client?

Member 9027346 10-Jun-14 5:12am

client

If you want client side information, why are you writing code that will only get server side information?

What does "not working" mean?

Member 9027346 10-Jun-14 5:13am

port list not coming

Andreas Gieriet 10-Jun-14 5:59am

What is "not coming"? The list is empty? Have you checked your Device manager if you have Serial Ports at all on your PC? Do you have the right permissions to ask the system for that information, i.e. does your call throw any exception?

Me:
Communication ports of which computer? The server? The client?

OP:
client

In that case go back and learn your lessons about web applications from the beginning, but now listen to the teachers!
The code you presented runs on the SERVER machine!!! So in any case you can not list the com ports of the client!!! But for your consolation you can't read com ports from a web page on the client anyway...
Take a free advise - rethink what do you want to do and for what and do not try to write code before you have a design worth of it...
