Recovering Win3.1 Data

Don't forget, with a technique like that there is no need to limit it to (eg) serial-port speeds; the limitations will be the software on each end, the response time of the LED, and the response time of the phototransistor; these might well permit megabit-plus rates. 420MB at one megabit, unrealistically assuming no framing or error loss (ECC, retransmit, whatever), is under an hour. Cut the speed to 100Kb and double the data for framing and error loss, and my calculation says 19.57+ hours, still less than a day. I don't know about the original poster, but I wouldn't consider that out of the question at all. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
