Settings ICOP-1800 PC-104 Multi RS-232 Module under Linux.

1. Using jumpers set IRQ and port addresses on the card.

2. Redirect the IRQ in BIOS from PCI/PnP to ISA/EISA.

3. To launch the driver insert in the file /etc/modules

4. Set port parameters. E.g., for COM3 to COM6:
( we assume that 2 ports is allready on the board)

  setserial /dev/ttyS2 irq 5 port 0x0280 uart 16550
  setserial /dev/ttyS3 irq 5 port 0x0288 uart 16550
  setserial /dev/ttyS4 irq 5 port 0x0290 uart 16550
  setserial /dev/ttyS5 irq 5 port 0x0298 uart 16550

Is the devices ttyS4 and ttyS5 does not exist create them
with MKNOD as below:

mknod /dev/ttyS4 c 4 68
chmod 660 /dev/ttyS4
chgrp dialout /dev/ttyS4

mknod /dev/ttyS5 c 4 69
chmod 660 /dev/ttyS5
chgrp dialout /dev/ttyS5
