It seems to me that AT command is a tricky option that you want to use only when you are dealing with embedded systems or something.


I am using freebsd script as reference (https://svnweb.freebsd.org/base/head/sys/conf/ldscript.amd64?view=markup), assuming that it contains some
subset of features that is reasonable to implement. It uses AT. It definitely looks tricky feature, but it was easy to implement, so I did it because
assumed that supporting it is better than ignoring or something.
Though it would be interesting to know how much is it important to have and can it be replaced with something/ignored or not (I don't know answer on this question).
