Been Busy Copying files

The Ser-USB device loaned to QL Heaven has looked like this most of the last week. The activity LED and incandescent blue as it transferred around 128MB of files in several loads form the hard drive of the QL on to a QXL.win file of the laptop.

Ok its not exactly lightning speed even at baud 115200 but it is practicable and works. Are there any other uses for this amazing bit of QL hardware?
