From 8a97586e9445a60e355dea13aa87885ab3dcb277 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Antti=20Sepp=C3=A4l=C3=A4?= Date: Sat, 8 Aug 2015 07:44:38 +0000 Subject: [PATCH] uqmi: Add get-current-settings command-line switch MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Adding --get-current-settings switch which can be used to query ip-settings among some other useful data obtained from remote end when connected. This is mainly useful with modems which do not provide a dhcp server for nameserver or ip-information (especially in ipv6 networks).
