Yes this is possible.
The xmit/rcv pairs need to be crossed. If your local networking shop
don't sell the X-over cable or can't make it up for you, then take a
regular cable a swap the 2 pairs yourself. Note that pins 1 & 2 are
a pair and pins 3 & 6 are a pair.
PC1 ------------- PC2
1 -------------- 3
2 -------------- 6
3 -------------- 1
6 -------------- 2
Easy to do if your'e handy with a soldering iron and a multimeter.
Probably should cover the individual connections with black electricians
tape or other insulating material (heat shrink tubing).
