I have my a1200 connected to xp pc sharing internet and works great all you need is nullmodem cable,ON AMIGA miami 32b(i think other versions work but i always had this)and artser.device ,ON THE PC proxy server (i use proxy from analogX its free but very good) the only limitation is that miami work for 1 hour since its demo and you have to dial the connection again but it does not expire if you need help to setup the connection on both sides let me know
