Connect to Windows from Linux using NetCat

Hi

Need help to connect from Ubuntu to Windows using NetCat nc
I can not get my script to send new-line

Her is what I have tried

(sleep 2 ; echo user ; sleep 1; echo pass; sleep 2; echo netstat) | nc -t 10.10.10.34 23

gives this output

��%������'������Welcome to Microsoft Telnet Service

login: user44passnetstatroot@magnus 

Also tried echo "user/n"

This is the sort of thing you'd use expect for. Especially autoexpect which can read an interactive session and turn it into a script...
