Inappropriate ioctl for device
I'm trying to configure my Geeetech I3 pro C with Repetier-host on my new computer.
I was previously using another PC with Debian 8 (Stretch) and the printer was working well. However the computer crashed due to hardware issues so I'm moving to a brand new computer.
This computer is a Dell laptop G5 and I'm running Debian 9 (Buster) on it.
I have configured the printer settings from Repetier following this link : http://www.geeetech.com/Documents/Geeetech Prusa I3 pro&pro B User Manual.pdf
After the first attempt to connect to the printer I had a permission denied error which is normal as my user wasn't yet into "dialout" group.
After adding my user to the group "dialout" and restarting Repetier-host, I now have the following error : "Inappropriate ioctl for device".
Does someone know how I could fix this ?
Is it possible to increase log level in order to go further into debugging ? (don't really want to use strace on repetier ^^)
Is there a way to connect directly to the printer using serial-terminal emulator (like gtkterm or minicom) ?
I'm well used to linux but I am very new to 3D printing and Repetier-host so I miss many information and basic knowledges.
Don't hesitate to ask me for more details if some are missing (and there certainly are).
Thanks in advance for your help.
