In order to to use debugger capabilities to interact with the device under test
we want to implement an auxiliary that can do that

• The user is able to read an address or a symbol within a running application
• The user is able to overwrite an address or a symbol within a running application
• The user is able to halt the program (like breakpoint)
• The user is able to watch for an address change or symbol value change
