   Note that you'll need hardware to convert the userport's TTL levels into   
   either RS232 levels or current loop signalling, depending on what the   
   teletype requires.

   If need to do this on a Commodore 64 then you'll nned to hack up the game   
   in some way to use the serial port.  As mentioned in other posts you might   
   be able to use BASIC's CMD to redirect the game's output to the serial   
   port, but there's no command for redirecting input.  As I recall the   
   early Infocom games for the C64 used the standard kernal I/O routines,   
   and it's not too hard to hack the later Infocom games to also use them,   
   so it wouldn't be that difficult of a hack.  Still you'll need to know   
   6502 assembly.   
      
   If you're just trying to a get a text adventure to work a on teletype   
   then your best bet would be use one of the Infocom Z-machine emulators   
   (eg. Frotz) on some sort of Linux, Windows or even MS-DOS computer with   
   a standard RS232 serial port.  You may still need some sort of hardware   
   to convert standard RS232 levels to the current loop signalling many   
   teletypes used.
