It's not impossible, but the hard part will be creating a naming infrastructure so the user can specify the appropriate serial port if there are multiple (non-console) tty devices present on the system. My suggestion would be to get it working using a userspace daemon, and then putting in the kernel code to open the serial port without a file system. It certainly can be done, with roughly the same techniques that are used to mount the root file system in the non-initrd case. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
