Comments:

I've never programmed in pic assembler but i think this is a great project and would be glad to help in anyway i can....i saw there are many comments in the source code that are in russian maybe?...maybe if you could translate them to english it would encourage more people(me included hehe) to help up! keep up the good work! James Newton replies: Anyone who speaks Russian and who is willing to translate the comments to English would be very strongly thanked.
linladn@yahoo.co.in " a nice code to start the thread of TCP concept with microcontroller too. looking forward for further enhancements.

" James Newton replies: Thanks, and please let us know if you find any resources or do any work on it yourself.

Questions:

how do you connect to the www server after pluging the rs232? James Newton replies: Send a standard HTTP request. See the screen shot for what to request.
karolisonline@hotmail.com asks:
Can this microserver be connected directly to the lan(to the switch), because I am thinking about ping server, some device that has an Ip and is able to echo ping from server.
Can this your device do it - responde to ping?
Thank You for the answer.

James Newton replies: This requires a SLIP connection.
it is really amazing.
but what could be the applications of storing only two links in a pic?
can we interface it with a device and control the device thru internet?
thanks
James Newton replies: Of course... this code is intended as a starting point.
