did you try to have two nios2-terminal connect? you might have conflict at the nios2-terminal because of the single com port that is connected, but not the nios ii because the sopc builder will take care of the switching between multiple master to a single slave.

Hi niosdii,

what is this "Did you try to have two nios2-terminal connect? You might have conflict at the nios2-terminal" i could not understand what is that nios2-terminal connection!!!!
