What is P-Scan?
P-scan is a port scanner that allows find about which port 
on a local network are open and which services are running
on them. It is very much configurable and also suport hostnames
resolution.

this software is pretty easy to use and has a very basic 
and intuitive graphical interface.

To start scanning, you first need to set three parameters,
which are :

1- TimeOut: that refers to the sockets used to communicate
with the network.P-scan allows you to set this parameter
manually. 

2- Number of threads: Windows XP for example is an operating
system that supports 'multi-threading'. Basically, threads are 
sub-processes that are assigned a 'task' by the system,
and none of them have to bother about what the other threads 
are doing unless specified.
So, if multithreading was not yet supported, you would then
you would not be able to execute anymore than a single part of 
a program and wait for it to stop until you can then do something
else with this program
If you ain't so sure about the number of threads you should use 
to get optimum result, then the best choice would be to leave it
to 64

3- Time between threads: Threads can be numerous and fast, very fast.
And sometimes it may happen what you can call a collision.
So to prevent this, P-Scan uses a timesleep function, which determines 
the amount of time the program waits until it assigns a new thread.

All those three settings, the value you will assign to them will depend
on your computer ressources very much.
It is likely that you have to perform a few series of tests before you can 
'tune' the program up.
Warning : If you set the socket timeout very low, like 1 or 2 for example,
in much cases it will result in a higher speed of execution, but at the 
same time, not all open ports may be found.
So you really have to perform a few test to kinda get a 'feel' on it,
and see what is best for your system.
if you yourself have more that one computer at home on which you can use 
this program then you will probable realize how much the capabilities of
this program are dependant with the system's self ressources.

Now, to save the output of a session, simply go to File then Save.
