CSQ is not unsolicited, so you'd need to poll it.  Not a good idea.

I suggest you simply support this ^RSSI notification, it looks like it has =
the =

same 0-31 range as CSQ.  Also, sometimes values from vendor-specific comman=
ds =

differ from CSQ, so if a query of ^RSSI is supported, use that.

ModemManager has done more work integrating ppp devices, poking around ther=
e =

can get you some hints.
