is this possible,
is there some sort of code that can make this happen

It sounds like you need a custom-built circuit, as pins 2 and 3 are normally signal lines for send and receive on an RS-232 port.  Perhaps http://forum.allaboutcircuits.com/showthread.php?t=5451 will give you some ideas, if you are able to make your own circuits.  Also take a look at http://www.tkk.fi/Misc/Electronics/circuits/rspower.html

Callandor:
that's a reasonable answer,
on the website http://www.windmeadow.com/node/4
it appears that I would have to make my own circuit and use the RS232 to initiate the circuit,
it appears that it is not possible to get the result that I want directly from the RS232,
if this is the case, it is better to simpy buy another cash drawer as I don't have the time to build a circuit
