I have tried to cat /dev/ttyS5 after setserial /dev/ttyS5 port 0xd800 irq 11 [ I tried 0xd400 and 0xd800] and everything went to cat: /dev/ttyS5: Input/output error So, maybe this card is not 8250 compatible :-( The card has one region of size 128: Region 1: I/O ports at d400 [size=128] I think that it is EEPROM, because there is a driver for EEPROM on this PLX chip somewhere on the Internet (I do not have that link here). -- Pavel Janík I think I started with hitting C-h a lot. Really a LOT. -- Kai Grossjohann in gnu.emacs.help about Emacs knowledge - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
