But the "^NDISSTATQRY" command isn't implemented on all modems
implementing "^NDISDUP" and "^DHCP", is it? Shouldn't you fall back to
^DHCP in case ^NDISSTATQRY returns ERROR? Or is this command
implemented on all modems where we currently need to use AT commands? I
don't have any modem without QMI and/or MBIM, but none of the two QMI
modems I have support ^NDISSTATQRY:
