Dear All,
I'm trying to enable a four-port serial card (you'ld be
surprised how many pieces of equipment still have
RS232 interfaces). I'm using Fedora 7 on a quad-core
Intel Q6600 machine with 4GB of memory.
#/sbin/lspci -vvvx shows the following:
07:01.0 Serial controller: NetMos Technology PCI 9845 Multi-I/O Controller (rev 01) (prog-if 02 [16550])
Subsystem: LSI Logic / Symbios Logic 0P4S (4 port 16550A serial card)
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Interrupt: pin A routed to IRQ 21
Region 0: I/O ports at 1030 [size=8]
Region 1: I/O ports at 1028 [size=8]
Region 2: I/O ports at 1020 [size=8]
Region 3: I/O ports at 1018 [size=8]
Region 4: I/O ports at 1010 [size=8]
Region 5: I/O ports at 1000 [size=16]

30: 00 00 00 00 00 00 00 00 00 00 00 00 0a 01 00 00
when I do a setserial I get this:
# /bin/setserial -avg /dev/ttyS*
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x1030, IRQ: 21
Baud_base: 115200, close_delay: 50, divisor: 0

/dev/ttyS1, Line 1, UART: undefined, Port: 0x02f8, IRQ: 3

/dev/ttyS2, Line 2, UART: 16550A, Port: 0x1028, IRQ: 21
Baud_base: 115200, close_delay: 50, divisor: 0

/dev/ttyS3, Line 3, UART: 16550A, Port: 0x1020, IRQ: 21
Baud_base: 115200, close_delay: 50, divisor: 0

Flags: spd_normal skip_test
Clearly /dev/ttyS1 is not OK, but I've no idea how to
set it up so it is OK - I'd be grateful for any help.
Thanks,
David Scriven
