Hello list, some of my serial ports are not working. ttyS0 mainboard's port doesn't work, ttyS[45] (PCI-express card) don't work, only ttyS[67] (PCI card) work correctly. I tried the different ports with my modems, a video terminal and my UPS, they work on ttyS[67] but not with the others - using the same configuration and permissions. Probing the modems (using hylafax's probemodem) makes the modem's leds blink, but will fail, on my VT i get hieroglyphics instead of a login.
Any ideas? thanks a lot for help, regards Paul

Here some info: setserial -ga /dev/ttyS? /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test
/dev/ttyS4, Line 4, UART: 16950/954, Port: 0xac00, IRQ: 18 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test

/dev/ttyS6, Line 6, UART: 16550A, Port: 0xd800, IRQ: 22 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test

ttyS4 was originally set to baud_base 1130000 like ttyS5, but setting it to 115200 didn't change anything.

the first one is the failing, second the working one

Hi Paul; For the mainboard port, did you check the BIOS to ensure it hadn't been disabled somehow? Also, what distro are you using?
