problems on reordering data from serial

Is there anyway of reordering the signals that have been received through serial? For example, I'm sending 1 2 3 and it is coming 3,1,2 or 1,3,2 or even 1,2,3. I want always the same sequence.

Please show the command you are using to write the signals, and the command you are using to read the signals.

I'm not using commands, only blocks in simulink. I'm sending 3 constant signals, 1 2 and 3 and I am putting a serial receive connected to a demux so I can view these three different signals. The problem is everytime I run the simulation the signals appear in different orders. That might some block so I can reorder these signals received..

It sounds like you are not mux'ing the signals before they get to the transmitter block.

Alternately you are not using a switch block clocked by time to select which signal is going to reach the transmitter block.

Remember to check that the datatype for the values being transmitted is the same as what you are pulling out. For example if your signals are double precision numbers that encode integers, then do not pull them off the receive port as if they are bytes.
