ISDN4Linux provides a fake modem emulation in kernel space. The Nokia phone drivers provide a user space manager which provides the interface.
So you've got precedents for both. If it's simply a case of splitting AT commands off from the data and spotting guard bands and +++ you might want to do it kernel side, if the second endpoint takes its own set of phone control messages I guess its hairier. - 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/
