https://bugzilla.kernel.org/show_bug.cgi?id=208959 Bug ID: 208959 Summary: USB-serial (mct_u232): bit7=1 when tty is set to cs7? Product: Drivers Version: 2.5 Kernel Version: 5.7.0 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: mslade@xxxxxxxxxxxxxxxx Regression: No I'm not 100% certain this is a bug, please let me know if this is expected behavior. I have hooked an old serial mouse up to a USB serial device, USB ID 0711:0230 (part of an circa 2000 Targus port replicator) when I configure it with the appropriate 1200 baud and 7 bit char width, the bytes that come through /dev/ttyUSB0 all have bit7 set to 1. This behavior is in contrast to an old serial port on a box running a 2.4.19 kernel. Is there a standard for the value that non-data bits should be set to? -- You are receiving this mail because: You are watching the assignee of the bug.
