Looking at ifxmodem, I thought the prefix had something to do with
radio technology (please don't ask me why the "x" in front of "rat"
:-) )

As I told through IRC, I'm changing it to syscfg, as this is actually
the command name

I don't think so after poking other projects and testing with a huawei
E220. The second parameter for SYSCFG command means the acquire order
(https://wiki.archlinux.org/index.php/3G_and_GPRS_modems_with_pppd_alone),
so it's pointless here even if some other competitors explicitly set
to "gsm first" or "umts first" when setting the mode.


Thanks for reviewing.
