The retry loop seems to have cured the missreading.... If it dont get it the first time it tries 3 more times... I=3
I have also put :- If (Serial[1]=$F0) etc in brackets... Tides things up a bit.:-)

It seems to be working OK now

Thank you again for help....Maybe see you in Scunny on Monday ...!!!

THank you all others who helped..... Great Forum!!
