Sorry for sending on a new thread, I'm on a different machine so is
unable to continue the last thread.
That is just some puts() code to tell myself where the code is up to.
The function AFAIK is actually an empty function and does nothing
according to cpu/pxa/interrupts.c
I've tried 3 terminal program, 2 in windows (HyperTerminal & Tera Term
Pro) and 1 in linux (minicom). Althought minicom is known to have
problems, it is only transmission of file across tftp that is
problematic I think.
WD did suggest that it might just the flow control.
I've tried all 3 settings available, Hardware, Xon/Xoff and None.
All 3 of them have not worked.
I've been trying to see where the code stops and it seems to stop in
rcode = parse_stream(&temp, &ctx, inp, '\n');
this is in common/hush.c line: 3154
Continuing with the hunt :)
