Sometime ago I upgraded to FC3 from RedHat 9 to, among other reasons,
get my VScom PCI 2 port serial card working.
(RedHat 9 required a kernel re-compile)
Anyway FC3 made it work. The two ports have been working for sometime on
/dev/ttyS4 & 5. Now, inexplicably (after a reboot test) the 2 ports
insist on using /dev/ttyS14 & 15.
I removed my rc.serial ...
<reference>
[root@billinux ~]# cat /tmp/rc.serial
setserial /dev/ttyS4 port 0xeca8 autoconfig
setserial /dev/ttyS5 port 0xec98 autoconfig
</reference>
... and still they come up as ttyS14 & 15.
Somehow, the kernel must be doing this. But how? ACPI? Where is the
config?
How might this have changed? yum?
Can I still use a rc.serial?
How can I get the ports permissions set to 666?
<reference from: dmesg>
ACPI: PCI interrupt 0000:00:04.0[A] -> GSI 25 (level, low) -> IRQ 177
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS14 at I/O 0xeca8 (irq = 177) is a 16550A
ttyS15 at I/O 0xec98 (irq = 177) is a 16550A
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
</reference>
I checked /etc/sysconfig/hwconf and found:
class: MODEM
bus: PCI
detached: 0
device: ttyS4
driver: unknown
desc: "Titan Electronics Inc VScom 200L 1 port serial adaptor"
vendorId: 14d2
deviceId: 8020
subVendorId: 14d2
subDeviceId: 8020
pciType: 1
pcidom: 0
pcibus: 0
pcidev: 4
pcifn: 0
I then ran $/usr/sbin/kudzu -p and it said:
class: MODEM
bus: PCI
detached: 0
device: ttyS14
driver: unknown
desc: "Titan Electronics Inc VScom 200L 1 port serial adaptor"
vendorId: 14d2
deviceId: 8020
subVendorId: 14d2
subDeviceId: 8020
pciType: 1
pcidom: 0
pcibus: 0
pcidev: 4
pcifn: 0
again, this device is a 2 port serial card. So now I'll reboot and see
what port it gets assigned ...
rebooted and ttyS14 & 15 were assigned again.
output of lspci is:
[snip]
00:04.0 Serial controller: Titan Electronics Inc VScom 200L 1 port
