I just dug out one of my old dongles and plugged it into a debian
testing laptop.

The mode switch seems to be automatic, which is what I remembered, and
someone else said had been true of recent kernels.

Here is an extract from dmesg:

Note the connections to /dev/ttyUSB0 & /dev/ttyUSB1. You use these in
the chat/ppp scripts. I can probably dig out my versions somewhere if
you need them.

I also dug out an old ZTE dongle and plugged that in. From dmesg:

Again, note the /dev/ACM0, /dev/ACM1 and /dev/ACM2 nodes. The
corresponding ppp/chat scripts use these devices.
Again, I can probably dig out those if you really want them.

I assume that more modern dongles/modems will be similar.
