I have send IP packets with 2400A, 2400B and 800XA. Those modes have a sync word in each frame that is used to switch between data and voice frames. (And works out of the box with recent codec2 versions). It wouldn't be hard to send data with the other modems as well (as they are also just frames with bits) however there currently is no way to distinguish between voice and data, that would have to be selected manually.
