Actually you will need a crossover cable, Unless you are using a hub or
something. The problem is that they are both using the same 2(or more)
paths for trasmitting and receiving. A crossover switches them around.
Normal
comp 1 S --------------------------------- S comp 2
R --------------------------------- R
Crossover
comp 1 S -----------\ /----------------- S comp 2
\/
/\
R -----------/ \----------------- R
See the difference? With a normal cable its like holding a phone
upside-down.
