How can I redirect the console output to a telnet user.

I run our main application from init.d/rcS.
It uses printf's to display continuous program debug information that can
be seen on the serial ttySAC2 console.
I would like to be able to remotely view this information by a telnet
connection when needed.
What is the best way to accomplish this?
The telnet user can possibly activate some script or program.
I saw there is a ttysnoop program that I could not get to compile.
There must be a simpler way.
There must be several ways.

 Thanks
