[Fourlanders] FT-847 HRD DM780 audio interface question

[Bill Pence]

I think I found the root enough cause of the issue, but no solution yet.
HRD seems to use CAT command to TX, but I need to assert RTS.
As far as I can tell, the FT-47 does not use TX audio from th rear panel if
the CAT command is used to enter TX mode.

There is an option in HRD to us the RTS, DTR or both, but it does not seem
to work as I would expect. (Meaning I select RTS, but the line is not
asserted...)

dang software guys.

(BTW, we called it "root enough" cause since the true root cause for EVERY issue
is that Eve ate the fruit and gave it to Adam and he ate it, too.  It
has been downhill
since.)
