3.3 Linux Driver Installation
This installation guide describes the procedures to install the PCI serial board
in Linux kernel 2.x, 3.x and 4.x Please refer to “snx_Vx.x.x.x.zip” for driver
installation detail in CD Driver (Linux folder) directory.
: \ PCI_IO \ Linux
(1) Driver install
Please create a directory under root directory, e.g /temp, do commands:
# cd /
# mkdir temp
After get driver file "snx_Vx.x.x.x.zip". Copy file to /temp
directory, then extract and install, do commands:
# cp snx_Vx.x.x.x.zip /temp
# cd /temp
# unzip snx_Vx.x.x.x.zip
# cd /temp/snx
# make clean ; make install
*************************************************************
* If system is Suse 9.0 and errors occur when
* "make clean ; make install", do commands:
*
* # cd /usr/src/linux/
* # make cloneconfig
* # make dep
*
* then do "make clean ; make install" again in /temp/snx
*************************************************************

___________________________________________________________________________________
20
Load driver module, do command:
# modprobe snx
or
# insmod /temp/snx/driver/snx.ko (snx.o for kernel 2.4)
Check driver module, do command:
# lsmod | grep snx
Unload driver, do command:
# rmmod snx
(2) Device node creation
Each serial port has one device node which is named "ttySNX?",
maximum up to 32 serial ports.
This setp will be done when do "make clean ; make install", if
device nodes aren't in /dev, do commands:
# cd /temp/snx/snxmknod
# ./snxmknod
This will create device nodes in /dev.
If there are more than two boards installed, serial port device
nameing convention please refer to F1.
