Subject: PC/Beeb serial cable woe
Hi Kris,
I too struggled with this problem and spent ages getting one to work
nicely. Various people seem to have had flame wars over how this "should"
be done in the past - as usual the problem seems to lie in the fact that
PCs don't always work as they "should"!
So when I did I wrote up my experiences see:

It is the last article at the bottom of the page "Connecting a BBC to a
Linux PC" - Although it discusses Linux the cable works ok with a PC
running Windows too
Cheers
Dom
