From the way rev0 has been explained to me is that it will peak at 1.5mbs per second, however real world speeds are between 400 and 900kbs. You should go in and change the modem settings to the highest bandwith. Since it is a serial port connection. The highest it will go is about 1Mbps with serial if I remember right and then there is overhead with the packets which is why you get lower speeds. Its like usb 2.0 through put on sdcards they always say up to 480Mbps but it really is more like 13Mbps cause that is all the cards are capable of. Can't wait for rev 2. Hope uses another type of connection other than serial port.
