The VSPDL is supplied in two different versions:
 To install VSPDL you will need the following:
| • | LINUX system (kernel 2.2.x-2.6.x). | 
| • | Linux kernel headers/sources of the Linux kernel you are running now. | 
| • | binutils-2.7.0 or above. | 
 Further, you will need either
| • | gunzip-1.2.4 or above to process TAR archive, or | 
| • | RPM tool of your choice to process RPM package. | 
 The Virtual Serial Port Driver for LINUX (VSPDL) distribution includes the following:
| • | VSPModule - Linux kernel module that creates Virtual Serial Ports (VSPs) on your system (in lib/* of your distribution). | 
| • | VSPDaemon - interacts with the VSPModule, facilitates data transfers between the VSPs and the network (in sbin/* of your distribution). | 
| • | Documentation - current documentation set in HTML format (in man/* of your distribution). | 
| • | Sample configuration files (in etc/* of your distribution). | 
| • | VSPModule/VSPDaemon startup scripts ( in bin/vspm, bin/vspd of your distribution). | 
 To install from TAR archive:
| • | Login from console as a superuser (root). | 
| • | Copy the TAR archive into a temporary directory (i.e. /root/vsptmp): | 
| • | #cp ./vspd-1.00.tar.gz /root/vsptmp | 
| • | Unpack the TAR archive and go to the destination directory: | 
| • | #tar xvf ./vspd-1.00.tar.gz -z | 
| • | Install the VSPDL into /usr/local/vspd : #./install.sh /usr/local/vspd  (the shell script will install all files automatically): | 
| • | The script will check system dependencies for VSPModule compilation; | 
| • | The script will then compile the VSPModule; | 
| • | Finally, the script will install all files into their target location (/usr/local/vspd) and necessary startup shell scripts (vspd and vspm)- into /etc/rc.d/init.d/. | 
 To install from RPM archive:
| • | Login from console as a superuser (root). | 
| • | Go to the directory containing RPM archive and execute the following command: #rpm --install ./vspd-X.YY-linux.i586.rpm (you can also use any other tool of your choice to install RMP). | 
| • | RPM subsystem will check package dependencies and let you know if something is missing; | 
| • | If all dependencies check out successfully an installation directory will be created (normally, /usr/local/vspd-X.YY-dist); | 
| • | Next, the VSPModule will be compiled and installed into the package installation directory (normally, to /usr/local/vspd); | 
| • | Finally, the RPM subsystem will check the distribution installation directory and package installation directory to see if both were successfully created. | 
 If the VSPDL installs successfully, you will have the following:
| • | In /etc/rc.d/init.d/vspd and /etc/rc.d/init.d/vspm - standard UNIX startup scripts for VSPDaemon and VSPModule. | 
| • | In /usr/local/vspd/bin/* - VSPDL services (startup and VSPTty). | 
| • | In /usr/local/vspd/lib/vspm.ko - VSPModule. | 
| • | In /usr/local/vspd/sbin/vspd - VSPDaemon. | 
| • | In /usr/local/vspd/man/* - VSPD documentation. | 
  
 | 
Warning regarding LATEST Linux KERNELS (2.6.x, x>= 13): If your system can't load VSPModule and shows a "module not found" error after VSPDL installation, you have to add a string into /lib/modules/<kernel-name>/modules.dep: 
/usr/local/vspd/lib/vspm.ko 
and loader will have possibility to load VSPDModule.
