Sending a "Signal" to the Serial Port

How to send a signal to a cash drawer on the serial port to open

I'm creating a POS application w/ ASP (or PHP...depends if I learn it in time), and I need to be able to send a "signal" to the cash drawer after each transaction to open it.

I do not know what type of drawer I will be using, nor do I know if the printer is going to run through it or not (most probably through the parallel, but not sure at this point).

I know w/ ASP that I can program some command shell calls to open any sort of file...so, I'm not sure if I had an EXE that could be ran.

Basically, if anyone could provide any sort of suggestions, or maybe point me in the direction of tutorials, I'd really appreciate it.

Might be worth checking out OPOS (OLE for retail POS) ... this provides controls to drive many retail devices.

Just type "OPOS" into Google. There are plenty of resources kicking around for you to read through.
