Re: [Hamlib-developer] rig-multicast?

[George B. <geo...@gm...>]

It's still there, but right now it's on hold.  This and a couple of 
other features need some problems solved first.  The major holdups are:

1. Thread safety - Internally there is very little consideration of 
conflicts between threads.  The locking now is at the entry/exit level.

2. Error handling and recovery - Some of the error handling code affects 
state and data far outside of its scope.

As AA5SH wrote, the current way to handle multiple users is to use 
rigctld.  My setup is to have cqrlog configured to start rigctld, and 
then I tell cqrlog(via ctrl-J) to fire up WSJT-X (Improved), configured 
to use 'Hamlib dummy' as the rig on 127.0.0.1:4532

We may get back to the multicast and/or REST interfaces to Hamlib next 
year, but it will require some real design work (including some security 
concerns) before they can be generally used.
