I figured this might be a good place to ask this.

On my Linux Mint laptop, every time I want to enable CAT control for JS8, WSJT, FLDIGI, etc, I have to open terminal and enter " sudo chmod a+rw /dev/tty..." replacing the "..." with whatever serial device ID like USB0 or ACM0. I can't remember how I learned this trick, and honestly don't have a clue what it means. Is there some way to make this permanent?
I hope my question makes sense.

Ran "groups" and I see me listed.

Okay Kelly you gave me something to search for, I have a little reading to do and I'll hopefully figure it out.
Thank you.

sudo chmod a+rw /dev/tty..."? is setting "permission" ( rw sets read-write) I was setting it to 777 (full permission) "back" when I started using Mint, years ago.? With time/updates, I no longer had to set permission (don't know what changed).??

I am seeing issues on RPi5 OS64bit that I had on RPi4 when I went to 64 bit OS.? If only I could remember what I had to modify...
I will be looking back at emails (this group) as I know it can be fixed.? Still using RPi4, overclocked portable, but RPi5 IS faster + NVMe is fast too.
