What do you mean by "return STDIN of the program to the controlling console"? Do you mean send *stdout* of the program to the console? Or redirect stdin to the console once the Perl process is finished writing to the child?

Instead of doing the fork and pipe you can do: 

open(CHILD, "| $command") 
    or die "$command failed: $!\n";
