[Hamlib-developer] Question...rigctl timed out on receive, cannot see data from 746PRO

[jeff m. <wa...@gm...>]

Can anyone provide guidance on debugging this problem...

Here is a bit of log from rigctl.  This occurs during startup.

$ rigctl -m3046 -r /dev/ttyUSB0 -s 9600 -vvvvv 2> rigctl.log

<...>

rigctl report version 4.6
rigctl is connected to an IC-746PRO at 9600.
Using FTDI USB to CI-V adapter.
FTDI adapter works on IC-7300
Other adapters fail the same way (prolific, fake prolific, other chinese)
Oscilloscope in CI-V line shows Tx from rigctl and response from radio,
looks normal
Oscope only shows response from radio when baud rate correct...so reading
scope right

any ideas or suggestions?
