I don’t have an H44, heck I’m not even sure if the command even works on there but i don’t think it does since it came out a few months before the HR54 did.I believe that your H44 is the only Genie that can process that command. It does not work on a HR54 or Genie 2 (HS17), and certainly not on a client. All of my SHEF tools created over the years lie abandoned.
