+1 for this test.
If you have a volt meter, it might be instructive just to measure
what the radio is putting out on the serial out line.? It might
reveal a bad serial port driver on the radio, or a bad cable or
connectors.? Just sitting there, it should be something around -9
volts.? Measure between pins 3 & 5 on the radio, pin 5 being
ground, or pins 2 & 5 on the USB adapter end of the cable
(because of the null-modem swap).

Ok try this,

Open Terra Term (free download). Select the right port and
open the terminal. Select satellite mode on the radio. If
you’re sure you have everything set correctly then you should
at least see some garbage come up on the screen.? Set the
switch on Terra Term HEX and you should see the frequency of
the radio and sub VFO in the HEX.

I tried several FTDI chip serial converters with or
without null-modem cables. The coms are 9600, 8,n,2 with
or without dtr-rts activated. Seems there is no reply
from the radio when connected. RATS847 software can send
commands to the radio, like frequency changes, but when
I turn the Dial of the radio the frequency is not
changed in the program.

The serial number of the radio is: 9E180166.

I have read the manual thoroughly, and I'm fairly
used to this kind of problems with other devices. For
me, it seems that the RS-232 is not working as it
should. What can be done here? I'm thinking of a
Bluetooth interface connected to a data port of the
radio. Maybe Signal link can offer a solution with their
USB interface?
?
The intention is to use the radio for Satellite coms.

All suggestions are most welcome.
