I am trying to make a long null modem line.(30+ feet)  I know that there
are only 5-6 connections required but I am not sure of the pins.  I am
trying to use a 6wire phone line with no luck.  This is what I have tried :

Computer 1         Computer 2
    Pin                Pin
     2 ---------------- 3
     3 ---------------- 2
    4&5 --------------  8
     7 ---------------- 7
     8  -------------- 4&5

Is this correct? Do I need more connections?  Is it just my 
saudering(sp, I know) job?  Should I shield the cable? If so how?

Please help,

         John.
