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

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

Hi Mike,

Thanks for the quick reply,  There is only one serial port, and it is
ttyUSB0. dmesg show it as ttyUSB0.

I put a scope on the CI-V line and it shows the transmission from rigctl
followed by the response from the radio.  If I change the baud rate, the
radio doesn't respond. So, I think the characters are not getting
received by the dongle, linux, hamlib, or rigctl and can't imagine why.

There are two hamlibs on the pc, any weirdness there?  I have been playing
with building wsjtx from source.

   - /usr/local/bin/rigctl --version ... reports Hamlib 4.6~git
   - $HOME/ham/build/build/hamlib-prefix/bin/rigctl --version ... reports
   Hamlib 4.5.4

Both binaries work and fail to talk to the radio.

jeff, wa1hco
