I talk to my Newton and with its speech recognition module, it gives
me answers. However, it couldn't tell me what the pinout of the
connector was, and it seems to be quite in bad mood tonight.

It doesn't mean it will work, unfortunately.
I don't know about tblt. It may be channel 2 indeed (mdem definitely
is channel 3). The DMA subsystem channels are first for channel 0,
then I/R (one channel only), Audio, tablet and modem. But the tablet
is a totally different device, it's not handled by the SCC (like
audio). I guess we'll have to dig into the code to make sure that
tblt indeed is for channel 2.

Are you sure the J6 is after the line driver? I thought the line
driver was between the J6 and the interconnect port, i.e. that
everything on the J6 was at CMOS level. This is what my Newton told
me, actually.
