[Elecraft] K3 Serial Comms with Apple Mac ?

[Bayard Coolidge, N1HO]

 I am not sure what you're planning to do with "Serial" but when I'm using my K3/KIO3B withWSJT-X, I have the program configured for CAT Control on /dev/cu.usbserial-A5xxxxx at aBaud rate of 38400, 8 data bits, 1 stop bit, Handshake set to 'None', and PTT Method of RTS(set to the same /dev/cu.usbserial device), Mode Data/Pkt, Split 'Rig', and a 1 second Poll Interval.CONFIG:KIO3B is set to 'nor'.
Permissions for the port device file are set to 666 and owner/group is root/wheel.
You might also want to double-check About My Mac -> System Report -> Hardware -> USBto see if the K3 is showing up - mine is a 'General Purpose USB Hub' with a TI vendor IDwhich has a USB Audio Codec (Burr-Brown) and an FT232R USB UART whose serial numbermatches the device special file that WSJT-X is talking to.
Also, go to System Preferences -> Network and make sure that that port is not configured.(It most likely is not, but Murphy does very strange things at times!)
It wouldn't surprise me if Serial might have a permission problem/setting that's fouling you up,but that's just a SWAG on my part. I'm running Lady Heather through another USB line to myGPSDO without any fiddling on the macOS side, but you never know.

 One of the very popular serial communications programs available in the Apple Mac store is an application called “Serial”.  What makes this app nice to use is that it includes built-in driver interfaces for just about any USB-Serial or serial interface you could put on a Mac computer.

I decided to connect to my K3 using Serial.  But, I am having trouble getting the K3 to respond.  I know I have the right comm port and I know that the K3 can communicate over this comm port.  

Has anyone used Serial (the app from company Decisive Tactics, Inc.) to communicate with a K3 or any other Elecraft equipment?
