Data transfer to/from an external data medium
Before you can transfer data to an external data
medium, you must set up the data interface, See
"Setting up data interfaces".
Depending on the data transfer software you use,
problems can occur occasionally when you transmit
data over a serial interface. They can be overcome by
repeating the transmission.
