[Coco] megaread HOW TO ?

[coco at jechar.ca]

Thanks so I used:  date -t ; megaread < @/dd ; date -t
        to find that my SuperIDE had a MegaRead of 17 Seconds.

Replaceing @/dd with @/x0  I found that the
        JAVA drivewire server had a  MegaRead of 18 Seconds and the
        PYTHON drivewire server had a  MegaRead of 20 Seconds, this
        is through a USB port and with a 115200 baud rate.

I was surprised the Hard drive was not faster.

Charlie.
