"When the user types a character in the Hyperterminal window, the character does not go out the DB9 comm connector on the back of the PC, but goes into the debugger's SBUF instead?" No. If the user types a character in the Hyperterminal window, it does go out of the DB9 comm connector on the back of the PC - you need to connect that COM: port to the COM: port that the uVision simulator is using (you will need a crossover cable). The two COM: ports could be on the same computer, or different computers.
