Re: [Hamlib-developer] feedback from RC2800 rotator -- solved

[<si...@ta...>]

 
By having a look at the rc2800.c I eventually discovered rotctl was expecting a command echo prior to reply from device.Furthermore, while rotctl sends to the rotator <CR> terminated lines, it expects <CR><LF> terminated feedbacks. 
 
Just replying to myself in case anybody stumbles in the same issue in the future.
