I looked at this again: I always get the error message when specifying
"mdmbuf", whether I'm connected or not.
Anyway, I've (again) looked up the meaning of "mdmbuf" (it means use
DTR/DCD flow control), and this is not quite what I want :) . So my
solution now is to just leave out "mdmbuf" in /etc/ttys.

(Perhaps the driver just doesn't know about DTR/DCD flow control, and
`stty' silently ignores the error? "Device not configured" would
still be a somewhat stange error message...)
