Looking on the scope a buad rate of just 115200 seems to be fine, I'm
keeping to this as I can't predict the performance
of the inbuilt uarts. I assume that a modern PC will do 115200.

Yes, generally there is no problem. Everything depends on the total data amount and your required response time.

... Since starting this thread I found that Windows does not want to play
ball.

I know that the script side of things can handle detecting and
processing the data.
I know that the H/W can deliver the data at the rate required, it all
works under Linux
However it seems under windows I'm missing some aspect of the chain of
command, I do have to do more testing
to determine if there is any thing "on the wire" that could be giving
windows cause for concern.

I suspect my use of the flow control lines to indicate data available
may be causing the windows a problem.

Cant remember the fconfigure off the top of my head, I'll post it
later.

Yes, please do this.
And please try to describe briefly your communication requirements.
Who is the master, who is the slave ?
Do both sides send data synchronously/asynchronously (logically) ?
Fixed block sizes ? Required timing ?

Regards, Rolf.
