I'm trying to link my 82 to my 83 and transmit all of my programs to the 83. However, even if I do it the way the book says, with either the cable that came with the 82 or the 83, I still get a Xmit Error on both calculators, but at about the same time which appears to mean that they are talking. Any suggestions? Thanks, Wes Mills ---------- wesmills@poboxes.com Pager: +1 972 609-1585
