Well, sounds like the hardware is communicating.  If you type characters 
in, does it do something?  I think the problem is the terminal protocol; I 
don't think regular telnet supports it.  I think it is trying to negotiate 
some stuff, hence the ascii crap.  Look for a program that has the terminal 
settings that you need.  The link I gave you should document the necessary 
protocols.
