FAS usually improves the throughput on all sorts of dumb port cards. Or if there isn't much to improve, it loads the CPU a lot less during serial I/O than the sio driver. Especially, if you use the NS16550A UART chips. They are replacements for the NS16450 or 8250 chips usually found on dumb port cards. >What is the lastest version of these drivers?
