Simulator for MCS51

# Software simulator for MCS51

This screenshot demonstrates one of option dialog boxes and the terminal window. Terminal window simulates a terminal which is connected to the serial interface of the simulated microcontroller. Every character sent by the CPU is printed out in the terminal window (it does not matter if it is opened or not) and every time when you press a key in the terminal window the character will be received by the serial interface of the CPU (when the simulation is running obviously). During receiving of the character the cursor disappears from the terminal window and reappears when receive is completed. Echo is turned off in the terminal window which means that only simulated program can "write" into the window.
