1.login as "root".

2.install the driver package enclosed in the diskette:
# tar -zxvPf pccom_pci.tgz
the driver package will be copied to the directory: /usr/lib/dci/pccom_pci

3.make device nodes:
# cd /usr/lib/dci/pccom_pci
# ./MAKETTY ttyZ
the device nodes (ttyZ[0-31] and cuz[0-31]) will be created in /dev.

4.install the driver module:
# insmod pci_serial.o
The version information of this driver is "2.2.14-5.0".
If the linux version in your system is not the same,
please make sure the option:"Set version information on all symbols for modules" is disabled while re-building the kernel. Another way to solve this problem is to use "-f" option in insmod. # insmod -f pci_serial.o linux 2.2.14 to 2.2.18 are tested without any problem. It's the easier way.

5.You may add the command "insmod /usr/lib/dci/pccom_pci/pci_serial.o" in the rc file (like /etc/rc.d/xxx.rc)
