Switch RAW data read on/off

In raw connections the data may be come faster than it can be handled. For this the receiving can be switched of and on again.

Data during the off state are stored internally. They will be given after the receive is switched on again.

The switch on will declare the last received data as handled. The next receive will return the next data.

Incoming data during the off phase will be stored internally. They will be returned in the next receive call after the receiving is switched on again.

Often this will be used in sequence chains.

Example:

A scanner returns data.

Additionally something will be fetched from a controller.

After this the data will be written into a database.

All this can run for a longer time as the next data will come from the scanner.

So no data will be lost if they come in a faster rate the database can handle them.
