TMS570LC4357: SCI Communication

Part Number: TMS570LC4357

Iam  working  on  SCI  where   two SCI   send  and  receive  that  can  seen  through  dock light   application  one  SCI  i will connect   directly  through USB  from controller to  laptop  and  other  will be  connect   RS422  later  to  laptop  using  USB  . send  and  receive  is  happen, but  required   things  is  by  opening  two  separate  dock light , whatever i  send  through dock light  SCI1  will be  receive  and  display  in  second  dock light , vice verse   whatever send  through second  dock light  should  receive  and  display in  one  dock light  , i will attach my code also  kind help me to over come  from  this logic
