Keylogging in Ruby

I’ve been attempting (feebly) to build a nice Telnet server recently.  
One of my (many) difficult tasks is  
retrieving characters from the other side of the 'net with the client  
hitting enter.

ie…

prompt\> look Gr\_  
prompt\> look GrGrog taunts you a second time!\_

I’m trying to use keylogging to prevent this from happening. Several  
things I have tried…

1. Using raw mode on the client’s side, and then initiating telnet  
with repeated IO.getc()s.
2. Using HighLine creatively…  
IO.ask("prompt\> ") {|q| word \<\< q}

Neither of those solved any of my problems, though I was sure the  
HighLine one would’ve worked.

So does anyone have any ideas or suggestions of what might work?

Thanks,
