Thanks for your help Graziano,
I'm using a cable made by Dan Tassel/SPE and I think it is the same wiring as
your diagram shows.
I did finally get it working this morning. After comparing your diagram with
my wiring I was looking at software port configuration more closely and I
noticed that N1MM+ recommended having stop bit set to 1.. I had it set to
2. I changed it and everything started working. Also started working when I
changed it in the dxlab commander software.
My takeaway is that at the faster baud rates stop bit setting is not so fussy.
At the slower baud rates it IS fussy.
Thanks again,
Gary KT0A

Hi,
give a look at the attached PDF for a possibile solution.
I did this and it worked for me.
