I've created the following init file:
[root@gateway /proc]# cat /etc/rc.d/rc.serial
SETSERIAL=/bin/setserial
echo "Configuring serial ports...."
#
${SETSERIAL} /dev/ttyS0 uart 16550a port 0x3f0 irq 4 ^fourport
${SETSERIAL} /dev/ttyS1 uart 16550a port 0x2f0 irq 3 ^fourport
${SETSERIAL} /dev/ttyS2 uart 16550a port 0x3e0 irq 10 ^fourport
${SETSERIAL} /dev/ttyS3 uart 16550a port 0x2e0 irq 10 ^fourport
#
echo "done"
This produces:
[root@gateway /root]# setserial -gav /dev/ttyS?
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f0, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0

closing_wait: 3000, closing_wait2: infinte

But aprsd and other apps still cannot use any ports except ttyS0. Below is
the output from ioports.
[root@gateway /proc]# cat ioports

Both PCI: yes
onboard ISA: no, never
both ISA: yes, with hardware modification
one ISA, other PCI: no
BUT: I think this has nothing to do with that error-message. Can you post
'cat /proc/ioports' output?
