Well, it certainly looked like a serial port when it was probed - to the extent that even loopback mode worked. Hence I'd be very surprised if it wasn't there. It's the same test that's being applied as has been for the last 14 years to detect if a port is present or not. Maybe Ted T'so would be aware if it can optimistically discover ports? -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
