The serial link has been tested using hyperterminal and a windows
application, I am now constructing a linux application using Ada
rather than C sharp which was used for windows. The parity / 8 bit

serial communications and could confirm it was all working etc or had
a suggestion on why etc. Thanks for your help Brian
