Unix Chat thru TELNET - newbie

Hello all,
I am new to Linux here..am doing my 1st year engineering with majors in computer software. This is the first time I am encountering a UNIX system in school to work practically. I was just through the basec Linux Terminal commands of creating new file, editing, shell programs etc.
In my school the UNIX lab goes like this..Redhat Fedora linux distribution is installed standalone in one computer..and ther other computers are networked to it. Say 9 computers run Windows and the 10th one runs Redhat. The 10th one acts as the server as per the information given by my professor. Students work on the other 9 computer with WIndows...and Prof works with the 10th. Generally we are instructed to go to Run> and type "telnet 10.1.2.150" ..after pressing enter, a new black window opens where we type in the Username and password to login to the UNix server. The point is all the other 9 computers use the same username and password for logging in to the unix server. There is a separate directory named "pmrcse" for our department within which we create our files, and other things using unix commands. All these runs within that telnet window. When I type the "who" command, I see the following:
root pts/0 Apr 23 10:43 (:0)
root pts/1 May 6 18:19 (:0.0)
pmrcse pts/3 May 6 18:20 (10.1.2.21)
pmrcse pts/5 May 6 18:23 (10.1.2.10)
pmrcse pts/7 May 6 18:34 (10.1.2.11)
pmrcse pts/9 May 6 18:21 (10.1.2.4)

From this I guess that 4 computers out of the other 9 windows systems have connected to the Unix server thru telnet.
My system is the one with the IP 10.1.2.11 pts/7
""Now if I want to chat with the other system , say pts/9 using the "talk" command or "write" command.. How do I do that?""
I tried entering "talk pmrcse@10.1.2.4" ..but its wasnt fruitful..Is there any feature that need to be enabled in the Redhat system for using the "talk" command?

Thanks in advance!

pts_source

PTS_SOURCE(1)						       AFS Command Reference						     PTS_SOURCE(1)

NAME

       pts_source - Read pts commands from a file

SYNOPSIS

       pts source [-file] <file name> [-cell] <cell name>
	  [-noauth] [-localauth] [-force]

       pts so [-f] <file name> [-c] <cell name>
	  [-n] [-l] [-f]

DESCRIPTION

       The pts source runs commands from a file as if they were typed in pts interactive mode. The command can be run from the command line or
       interactively.

CAUTIONS

       Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts source command was only available on Unix or Linux and when OpenAFS was compiled with
       the supergroups option (disabled by default).  As of OpenAFS 1.4.5 and 1.5.23, it is always available.

OPTIONS

       pts source takes the following options:

       -cell <cell name>
	   Names the cell in which to run the command. For more details, see pts(1).

       -force
	   Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the
	   first error.

       -help
	   Prints the online help for this command. All other valid options are ignored.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or
	   -noauth options. For more details, see pts(1).

       -noauth
	   Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).

OUTPUT

       This command shows the output of each command in the file as if it were run normally.

EXAMPLES

       Here is an example of using pts source in a pts interactive session:

	  % echo examine admin > /tmp/commands.txt
	  % pts interactive
	  pts> source /tmp/commands.txt
	  Name: admin, id: 1, owner: system:administrators, creator: anonymous,
	    membership: 2, flags: S----, group quota: 20.
	  pts> quit
	  %
