Bruce,

One other thing that has come to light is that I need clear the buffer after
Code:
HSEROUT [dec StopHour[0],dec StopMin[0],dec StopHour[1],dec StopMin[1],dec StopHour[2],dec StopMin[2],dec StopHour[3],dec StopMin[3]
I gather this is required so that it places the correct variable in the right location in the application.

Any ideas
