Re: configuring a USB/Serial port

Glen,
Why not do this one at a time?
Why are you setting the 9600 speed for example?
and, if you run the STTY command what are you confirming as the tty settings? Clearly if the error says unable to run all of the options, one of them may be the problem?
As expressed, I simply  ran a search with your question.
speaking personally, very much so, I avoid this by getting hardware with actual serial and USB ports saves the mayhem lol.

Unfortunately, the below command does not work with or without the usb, using #0 or 1.
stty -F /dev/tty0 9600 +cs8 -cstopb -parenb
I still get the error
unable to perform all of the requested operations.
I have also tried it with less in the command with the same error, e.g.
stty -F /dev/tty0 9600

 Hi,
 A quick search of the question,
 how to set a serial port in command line Linux?
 Yielded the suggestion of tty0 or ttyusb0.
 Also that running stty should show you what the settings are currently.
