Hi Guys,
    Thanks for your comments. It would seem that my suspicion re the UART
emptying it's buffer were correct. Mind you I thought that the Pic @20MHz
would have had plenty of time to do the interim short bit of work but
obviously not in this case. It looks like I'll have to implement that buffer
after all. And I learned of a new command C command for windows  Sleep() (I
could do with a bit of that myself now!)
As per usual the piclist triumphs again.
Thanks again,
John
