Duplicating Data

It may be necessary to accept data from one source channel (e.g. a serial port) and store into two separate memory channels.

The individual channels may then send the data in two different directions to minimise the probability of data loss.

function duplicatestore(rec, chnl, tag)
 mem.write(1, rec)
 mem.write(2, rec)
end

x.chnl[1].src.onrecord = duplicatestore

Here, the function that is glued to the event for channel 1 will store the data into both channels 1 and 2.

Caution

Channel 2 should not be connected to another data source as well, otherwise its data will be interleaved with the duplicate data!
