A 3G USB modem is a lovely example of compatibility gone mad It runs an emulated PPP session over an emulated serial port over a serial port multiplex emulating multiple serial ports over an emulated serial port over a USB link which has perfectly good packet facilities into the Linux kernel which makes it look like a legacy modem device which is managed by a set of software tools written for 9600 baud modems Unfortunately fixing that has to start at the vendor firmware end, and that is a lot of interfaces for SMS, voice dialing, fax and god knows what else as well as data. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
