Hello

I'm unable to use my serial port.

Here's the output from a few commands

#dmesg | grep ttyS0
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS0: LSR safety check engaged!
ttyS0: LSR safety check engaged!
ttyS0: LSR safety check engaged!
ttyS0: LSR safety check engaged!

#stty -F /dev/ttyS0
stty: /dev/ttyS0: Input/Output error

#ls -l /dev/ttyS0
crw-rw---- 1 root dialout 4, 64 jun 15 10:16 /dev/ttyS0

Does anyone have any ideas how to remove this error?

Thanks
