MANY THANKS ONCE MORE FOR BEING THE ONLY PERSON TO REPLY - YOU ARE A HERO. Sorry to go on at length, but I hope this might save somebody else in the future a lot of frustrating time. Then this morning 'Bingo' and 'Alleluliah' back to my shed (more like a tip) rummaged around for two hours and found a collection of leads and adaptors - first attempt (it looks very Heath Robinson) but it works. Still off at a tangent I was able to load Scantcat pro 5 and AORSC from my old floppy disk collection that I resurrected from the loft both programs running on the XP machine but they too were not handshaking. I am embarrassed to say that I then got sidetracked taking the scanner to bits to ascertain which baud rate it was set at and at the same time using the reset button (several times), still no 'hand shake'. The program that you recommended will run on both, however the AOR 3000A would not 'hand shake' using a brand new lead purchased specifically for the task. What have I been up to? Well I have resurrected two old pc's from my shed and in the bits and pieces found a total of seven hard drives, one pc I set up with Windows XP and the other with Windows 7 Vista. First of all my apologies for taking so long to reply to you - you were the only one who did answer my plea for help and I am most grateful for that.
