Let say you was unable to call ur fren, maybe he forgot to bring his cellphone and you know he is in the linux server room doing something, and you have permission to ssh to a particular server, then you can write him a message.
First of all, type "w" or "who" to check is he log on to the server and on which console. Let say he is on /dev/pts/1, so write him a message with
write hisname /dev/pts/1
you can start write your message now and end it with CTRL+D.
To have conversation both way check out talk.
To 'broadcast' to everyone on the server check out wall.
