This card comes from CompUSA - 2 serial, i parallel port. 2 Sipex
SP3243ECA chips drive the serial ports. Kudzu (RedHat 8.0) attempted to
install and says,

"The following modem has been added to your system:
        Oxford Semiconductor Ltd|OX176PCI952 (Dual 16950 UART)"

So I choose configure.

from lspci: (nothing new from lsmod)
02:00.0 Serial controller: Oxford Semiconductor Ltd OX16PCI952 (Dual 16950
UART)
02:00.1 Parallel controller: Oxford Semiconductor Ltd: Unknown device 9523

from dmesg: (ttyS0 & S1 work fine)
ttyS0 at 0x03f8 (irq = 4) is a 16550A (nothing new first 2 lines)
ttyS1 at 0x02f8 (irq = 3) is a 16550A
PCI: Found IRQ 12 for device 02:00.0
PCI: Sharing IRQ 12 with 02:00.1
ttyS4 at port 0xa000 (irq = 12) is a 16C950/954
ttyS5 at port 0xa400 (irq = 12) is a 16C950/954

My RS232 mini-tester leds remain dark. Can 'setserial' make this puppy
work, or is a kernel upgrade needed (currently 2.4.18-14) ?
I am studying the http://en.tldp.org/HOWTO/Serial-HOWTO.html
Google pulled up recent messages on this chip from LKML.
