From the computer (application to be exact), you send a signal to the printer to kick the drawer open but is there a confirmation signal from the printer going back to the computer that it successfully opened the drawer (not just successfully carried-out the command) ?

The cashdrawer is SERIAL, you'll need to connect it to a COM port. The
software you're using has to be capable of sending data to the COM port
the cashdrawer is connected to when the cashdrawer needs to be opened.
From the site you mentioned:
Be sure drawer lock is not engaged.
Exit your system to a DOS prompt. Type the following commands (substitute
the correct com port for com1):
The cash drawer should open.
About the cashdrawer RJ11 connection on the printer: You can connect any
solenoid driven cashdrawer to this port. The port uses pin 2 and 4 for
the voltage output, which is normally 24V on Epson receipt printers.
Sending a specific ESC character (every POS software should be capable of
doing this) to the printer will be recognized by the printer and the
printer puts 24V on the 2 pins mentioned for 300ms and voila, the drawer
