AT send delay set to 0 in port probings

[Brent Sink]

> Hey Dan, Brent and everyone,

> The second patch sets up send-delay 0 for the u-blox plugin (both during probing and once the modem has been created), so that the SARA-U260 can be properly detected.

Which branch should I be applying the patch to?  If I apply the first patch to the master branch and build, it does compile, but when I run I get a segmentation fault.  If I undo the patch and run again I don't receive the segmentation fault.  It seems to be related to the first patch for some reason... any thoughts on what I'm doing wrong?
