I'm very new to Linux and CQRLOG.
I was having no luck getting the PC to key my rig on CW. Now I've got it working. Here's what I did to key my FT-1000D.
I kept seeing references to cwdaemon, but had absolutely no idea what it was used for, so I decided to investigate. cwdaemon is a utility program that allows the PC to key the rig using either the parallel or serial port. In my case, I key from the parallel port. Years ago, I built a small transistor switch interface (right out of the CT and later, N1MM logging program's instructions) and use that to key the radio. It's worked flawlessly for years in the Windoze world, but no luck with Linux and CQRLOG, or so I thought.
I searched (Linux Mint 17.2) ADMINISTRATION, SOFTWARE MANAGER and typed in: cwdaemon and hit the search button. There is only one result returned and that's cwdaemon. I installed it and made NO changes to any of the default settings in CQRLOG's, Preferences, CW interface, cwdaemon settings.
Default CW speed: 30WPM
That did it! My normal keying speed during any CW contest is between 25 and 35WPM. The program is sending perfect CW with no Winkeyer or K3NG Key. Just straight out of the PC and into the key switch interface and right to the key jack on the rig. I know CQRLOG is not a contesting program, but at least I've got it working and it's completely usable.
Best of luck,
