4.8 Communication screen 

The right side of the main window shows the communication between the computer and the development kit. 
Each time the user sends a command, it appears in the screen, followed by the reply of the DVK90121. 
The user can specify the number of displayed lines in the “Lines to show” window. It was set up to make sure 
the most recent command or reply are displayed without scrolling. Moreover, it is possible to erase the screen 
by pushing on the “Clear” button.
