I know that I've successfully used the port in the past with some version of 2.4.x that is now WAY old but that's the best I can come up with as I no longer have those kernel compiles around. :/ Under 2.4.x I used the pcmcia-cs package rather then the kernel modules. The end result though is thesame and I'll concentrate on 2.5.x (primarily 2.5.49 but it doesn't work under 47 either). Under 2.5.x the problem is that whilst the serial side of my Xircom RealPort is detected as ttyS15: Nov 18 22:58:27 theirongiant kernel: PCI: Enabling device 02:00.1 (0000 -> 0003) Nov 18 22:58:27 theirongiant kernel: ttyS15 at I/O 0x4080 (irq = 10) is a 16550A It does not work and any access to it results in an I/O error as can be seen from this minicom strace: ... open("/dev/ttyS15", O_RDWR|O_NONBLOCK) = 3 fcntl64(3, F_GETFL) = 0x802 (flags O_RDWR|O_NONBLOCK) fcntl64(3, F_SETFL, O_RDWR) = 0 ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff6a8) = -1 EIO (Input/output error) ioctl(3, 0x5415, [0]) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff638) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_START, {c_iflags=0x1, c_oflags=0, c_cflags=0x40013cb2, c_lflags=0, c_line=1, c_cc[VMIN]=1, c_cc[VTIME]=5, c_cc="\x00\x00\x00\x48\x0e\x05\x01\x08\xae\x07\x08\x00\x00\x00\x00\x00\x00\x00\x00\xcc\xf6\xff\xbf\x86\x1a\x06\x08\x03\x00\x00\x00\x00"}) = -1 EIO (Input/output error) ioctl(3, 0x5415, [0]) = -1 EIO (Input/output error) ioctl(3, 0x5418, [TIOCM_RTS]) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff5d8) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_START, {c_iflags=0x31000000, c_oflags=0x40000860, c_cflags=0x88072030, c_lflags=0x40013420, c_line=25, c_cc[VMIN]=64, c_cc[VTIME]=23, c_cc="\x23\x07\x40\x48\x0e\x17\x40\x5c\xf6\xff\xbf\x94\x30\x12\x40\x05\x00\x00\x00\x5c\xf6\xff\xbf\x3b\x15\x06\x08\x03\x00\x00\x00\x00"}) = -1 EIO (Input/output error) alarm(0) = 4 rt_sigaction(SIGALRM, {SIG_IGN}, {0x8062744, [ALRM], SA_RESTART|0x4000000}, 8) = 0 stat64("/dev/ttyS15", {st_dev=makedev(3, 6), st_ino=7471, st_mode=S_IFCHR|0660, st_nlink=1, st_uid=0, st_gid=20, st_blksize=4096, st_blocks=0, st_rdev=makedev(4, 79), st_atime=2002/11/18-15:45:59, st_mtime=2002/11/18-15:45:59, st_ctime=2002/11/30-12:04:26}) = 0 ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff668) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_START, {c_iflags=0, c_oflags=0x3de80e9a, c_cflags=0x800, c_lflags=0x1d2f, c_line=0, c_cc="\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xec\xf6\xff\xbf\xf3\x16\x06\x08\x03\x00\x00\x00\x00"}) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff668) = -1 EIO (Input/output error) ioctl(3, SNDCTL_TMR_START, {c_iflags=0, c_oflags=0x3de80e9a, c_cflags=0xc00, c_lflags=0x1d2f, c_line=0, c_cc="\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xec\xf6\xff\xbf\x36\x17\x06\x08\x03\x00\x00\x00\x00"}) = -1 EIO (Input/output error) ioctl(3, 0x540b, 0x2) = -1 EIO (Input/output error) ... My /dev/ttyS15 entry is: 0 crw-rw---- 1 root dialout 4, 79 Nov 18 15:45 /dev/ttyS15 All this was done as root. Now I'm sure I got the minor/major right as devices.txt defines ttyS0 as 64 and ttyS191 as 255 (64+191) and as such ttyS15 should be 79 (64+15). Again, if you need any extra info, yell.
