I don't quite understand the MAX3232 chip

From what I can gather it is a chip used for transmitting and recieving serial information to a picaxe from a computer terminal, I believe it is similar to an XBee.
Now what I don't understand is how to put it together on a board, as in I understand the serial input from a computer and how to arrange the capacitor and where to put the volatage in and earth but what I dont get is where do I wire in the pins responsable for transmitting recieving and resting? Do I have to run them to an antenna or what do I have to do?

It's nothing like an Xbee in terms of an Xbee being wireless/having an antenna etc - it just has ordinary wired connections for the sending and receiving computers/PICAXEs.

MAX3232 is, in simple terms, a "RS232 voltage levels" (up to +/-25v in the extreme) to "logic voltage levels" (0v/3.3V) converter that also inverts the levels - random Googled picture

Possibly best that you explain why you think you need one - and why a MAX3232 (3.3v logic levels) whereas the most common version is MAX232 (5v logic levels) - to get best further assistance.
...the first pic on the page that eclectic references is normally fine for PICAXEs and most computers
