Looking for a way to telnet a few commands but not an entire telnet client

Hey, Im making an application to telnet my NAS and punch in some simple commands like chmod etc . Ive been googling for the last two hours and all ive found are fully functional telnet clients which i have no hope of integrating into my tiny application .

Can anyone point me in the direction of a telnet activex control or even suggest a way of using my application tto punch commands automatically into an existing telnet client like putty ?

Thanks
