I just wanted to connect to an IP via the com port modem. Can someone give some good documentation or a working code of it.

Actually you need to write a network driver for a card (preferably RTL8139 or i8254x). You can view their documentation here:
RTL8139

Datasheet: http://www.cs.usfca.edu/~cruse/cs326f04/RTL8139D_DataSheet.pdf
i8254x

After you've implemented the base driver you can then port lwIP to your OS.

It isn't easy and can't be done in small examples, networking is quite a complex area in OSDev.
