Page 23 of the help - physical leg 6 is from the computer to the chip and physical leg 7 is the chip back to the computer. I presume you mean for programming. For general data transfer you can use any inputs/outputs. Go into the program editor, go to help and look at picaxe manual 1.

Most pins can talk to a computer. On an 08 or 08M for instance, serout works on pin 0,1,2 and 4 and serin works on 1,2,3 and 4. (P19 of the manual) I'm not absolutely 100%, but I'm pretty sure on the bigger picaxes that any output can be used as serout and any input pin can be a serin. The serin/serout instructions list any value from 0-7, but you need to look at pages 19 to 24 of the manual to see which pins actually exist - eg on a picaxe18 the inputs are 0,1,2,6 and 7.
