The  standard says 50'.  I am sure you can get away wit more depending 
on  the data rate you are using.  I have had no problems in the past 
with  using a 25 conductor ribbon cable serial cable 50' in length at  
19200


If you convert the RS232 voltages to Current Loop, you can go even farther,  
on twisted-pair conductors.  That's why MIDI uses current loop, though not  to 
gain distance, but rather noise immunity on stages full of solid-state  
lighting cables and megawatt guitar amps, while running at three times the speed  
of any modem (I remember when Bell Labs scientists proved theoretically that no 
 modem could exceed 9600 Baud thru a phone line ;-)
