DSY: Daisy Chain
Function
This command is used to redirect all the characters flowing 
through a given serial port (source port) to another 
(destination port), without interpreting the flow of redirected 
data.
Once the daisy chain mode is on, only the command used to 
discontinue this mode can be interpreted on the source port.
Redirection can be in both directions, in which case two DSY 
commands, instead of one, are required to allow bidirectional 
data flow.
