Hamlib is great and really achieved a lot. Very neat what clients can do with that library for sure.
But, all in one solutions sometimes get, um, interesting. cwdaemon defined a protocol. So, anyone can write a replacement, that tlf and others, can use. And they have. cwdaemon itself doesn't support every type of keying hardware. Nor did some of the alternatives that implemented the protocol. On my todo list is to read the hamlib rigctld protocol to see if it is a candidate for the same approach. No, I don't think hamlib should go away or anything like that. But, to do something custom, like have an application listed to the cwdaemon and rigctld ports and wring what it can from the KX3 or K3 CAT protocol might be interesting. Or something along those lines. Sounds like someone has already tried something along these lines. Interesting stuff. Drew n7da ps. A couple of years ago, when I looked at the cwdaemon protocol, I also looked at the packets generated by several different client applications. Some send more data than the protocol requires, and cwdaemon doesn't complain. IIRC, all had trailing nulls, some a single null byte and some several. So, I reported that in debug mode: https://github.com/drewarnett/pywinkeyerdaemon/blob/master/pywinkeyerdaemon.py#L126 On Wed, Nov 27, 2019 at 8:45 AM Nate Bargmann <n...@n0nb.us> wrote: > > Thanks for that, Olaf. > > Here is a crazy idea I had that someone might like to experiment with. > I thought of using a serial port multiplexer, assuming such a thing > exists and I found https://github.com/danielinux/ttybus as one of the > first hits, to have Hamlib and cwdaemon share the same port.
