* Setting this to zero means no delay but wait for an acknowledgement
* from the rig after a command. This is undocumented but seems to work.
* It's also the most optimal way as long as it works...

* The timeout is deliberately set lower than the time taken to process
* a single command (~ 60 ms) so that a sequence

* rig_get_freq();
