Just realized I forgot to CC: the original list on my reply below. I also have since realized that using the solution in my reply below, the SERVER *COULD* cause the register to open. On the server side, a script that connects to HTTP://ip-of-register-to-open:secret-portnum would cause the register to open as desired. So, this is just a simple modification of my original reply. You still write a socket listener app. that runs on the workstation where the register is connected, that is capable of opening the register on demand. Then, when the user using the browser does something to open the cash drawer, you run a script on the server that connects to REMOTE_ADDRESS:secret-port which makes the "listener" app. open the cash drawer. (Okay, so it's technically client based, but server driven.) A similar tool (the same listener app, even) could be used to send text to the workstation-attached receipt printer. It could be setup such that any text received on the port it's listening to, is simply echoed to the printer. So, now the server generates what needs sent to the printer and prints it by connecting (from the server) to the listener app., followed by a connection to the port that causes the drawer to open. -- Mitch -------- Original Message -------- Subject: Re: Re: How could I make the browser to send a command to a cash register...

There are lots of examples of socket listener apps. done in Perl (check Google), but the local app. would *not need* to be in Perl (that's just one I've used personally). Once the app. is running, simply connecting to http://localhost:secret-portnum *could* be enough to make the app. open the register (by sending the right command to the serial port). Using this technique, any HTML that references http://localhost:secret-portnum would open the register, regardless of how the HTML is generated. -- Mitch Man-wai Chang wrote: >>That 100% depends on how the cash register works.
