Sending command to GPIO Port

Command line program for opening a POS Drawer. ## Deliverables UPDATE 07.10.2009 - 16:22 GMT+1 After contacting the manufacturer, they have made a program for this function for me, using [login to view URL] . I will attach this program on this page. This program works. The new program needs to send both these commands right after each other, as a commandline program that the user never sees. [Button] Caption="Open" Address=0x48f Value=0x13 [Button] Caption="Close" Address=0x48f Value=0x1b I hope this new information will be of help. ----------------------- Hi! I have a POS computer with a RJ11 output in the back thats designed to connect a POS Drawer. This port is not an RS232 port, but a GPIO port. I need a command line program that I can run to open the drawer. Whats in the manual for the POS computer; To open Drawer: Write "13h " to I/O Port "48f"h I also got this from the producer of the POS computer; [Button] Caption="Open" Address=0x48f Value=0x13 Just ask me if you are wondering about something.
