What you post sounds very strange to me: ethernet cards have RJ-45 connectors while RJ-11 are phone plug-in. Any way you can't send directly strings to both types of connectors by batch scripts because they require a device driver as a go between. As far as I know cash drawers are accessed via serial port, but if they are planned to be conected via LAN, ethernet card is the right device. And last but not least, this is the plain DOS Forum that has nothing to do with XP or Win 98 systems.

MOst cash draws I've come across use a parallel port pin to fire them. You say "I tried sending dos commands to it, but doesnt open it." What would those commands be?
