Thanks to all who helped me fix my rs-232 problem......I am kind of imbarsed to tell you guys but the cable that plugs into M-5 on the main board is wired all wrong.....Its a factory cable , so I never supected it ....But after I got a connection manual from this site it was checked , and low and behold its not right....I made a makeshift cable...and now I can down load to memory.....once again thanks to all....
