wrote: 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

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?
Tom
Hi, It's not deactivated, running openSUSE 11.3 (x86_64), 2.6.34-12-desktop (default doesn't boot it hangs at EDD). Thanx, Paul -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
