I just found out that there are other kernel drivers using the serial port as well (e.g. the SLIP or PPP drivers). It seems that what I want to do (which is accessing the serial port from kernel space) is called a "line discipline". I found an article "Writing a Kernel Line Discipline" with code snippets on http://www.linux-mag.com/id/1891 (You can find a login to this page here: http://www.bugmenot.com) Is this the right way to go ? -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
