Firstly, many thanks to

Dennis Martens []
Chris Liljenstolpe []
David Evans []
John Bradley []
Mark Cain []
Gerald Combs - Unicom Communications []
David Robson []

Who offered scripts and different options to try.

Most of the options I had already tried, so I dug a little deeper into
the software on the PC and found that it was converting nulls and other
control chars to PC friendly characters like spaces and carriage
return/line feed pairs thus causing the conversion confusion.

Many Thanks
