Hi George.!

Aboute the question, I have alredy the solution, two uP's - thats it.
Probably difficult to answer that type of question on this
forum. It requires that other are more initiated in the application.

Aboute manchester-code, both yes and on.
I can send and receive signs between two hyperterminals at
the moment, but not 100%.
The reason is that the manchester-signals are flucturated
a little, (not stabile dutycyckle), depending on fading between two radio-units.
As I've solved it, -external interrupt, and dubbled the internal
interrupt, (capture mode), will not work properly, and will
probably never do.

I,ve get advice from soft-developers which have worked with
same solution, with very proper results, but to an PIC-uP.

They have, if I should try to explain, 10-dubbled the internal
timer, 96000 times/sec, fetch one sample each interrupt-time and
have made a sort of software-logic to process the data.
Parhaps I can get some help to convert these routines from
Pic.asm to 8051.asm, becouse i have to develop some harware-
job now, so we have somethig to offer our customer.
