Aside from the other posts in this thread, I'd also like to point out that: 
system("sstty +rs 1a12","/");

is very unlikely to work, unless you have a command called "sstty +rs 1a12", and you want to pass it the single argument of "/".

When you invoke the multi-arg system or exec or pipe-open, you assume complete responsibility for argument parsing, since no shell will decide that for you. The first argument will be precisely the command name (as found in the $ENV{PATH}, of course), and the remaining args are passed one-by-one (although a NUL character cannot be passed because of the underlying interfaces).

Perhaps what you wanted was: 

system("sstty","+rs","1a12","/")
