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!

telnetd

telnetd(8c) telnetd(8c)

Name
telnetd - DARPA TELNET protocol server

Syntax
/etc/telnetd

Description
The server supports the DARPA standard TELNET virtual terminal protocol. The TELNET server is invoked when receives a connection request
on the port indicated in the TELNET service description.

The server operates by allocating a pseudo-terminal device for a client, then creating a login process which has the slave side of the
pseudo-terminal as stdin, stdout, and stderr. The server manipulates the master side of the pseudo terminal, implementing the TELNET pro-
tocol and passing characters between the client and login process.

When a TELNET session is started up, sends a TELNET option to the client side indicating a willingness to do remote echo of characters, to
suppress go ahead, and to receive terminal type information from the remote client. If the remote client is willing, the remote terminal
type is propagated in the environment of the created login process. The pseudo terminal allocated to the client is configured to operate
in cooked mode and with XTABS and CRMOD enabled.

Aside from this initial setup, the only mode changes will carry out are those required for echoing characters at the client side of the
connection.

The server supports binary mode, suppress go ahead, echo, and timing mark. It also allows a remote client to do binary, terminal type, and
suppress go ahead.

Restrictions
Some TELNET commands are only partially implemented.

The TELNET protocol allows the exchange of the number of lines and columns on the user's terminal, but does not make use of them.

The terminal type name received from the remote client is converted to lower case.

The server never sends TELNET go ahead commands.
