Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello,

I have installed TeraTerm (under Wine) on Zorin Linux v.18. In this version, installation is very easy; you simply open the .exe file on Wine. The problem is that in TeraTerm I cannot find the serial port to which I have connected the Pico.

I have created the symbolic link to COM:

ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1

and I have given permissions for dialout:

sudo usermod -a -G dialout $USER

But the COM1 port does not appear when making a new connection in TeraTerm.

I have also tried with the /dev/ttyACM0 port.

Any clues?

Did you log out & back in so that the usermod takes effect?

Have you found this post?

https://superuser.com/questions/619528/how-to-convert-the-dev-ttyusbn-to-a-com-port-to-use-it-with-wine-in-linux

It looks like some systems need a tweak in the wine registry.

I assume you have logged out and back in again?
that's caught me out a few times :-)
