BTW, as topic says, i'm trying to connect to my PMAX=DECstation 3100. I 
don't have any other options, other than serial console. I've taken VRAM 
out of the machine (have heard somwhere that this way it will switch to 
serial console output). Right now I do get something from it using 
"printer" port as described below, but no more than that... If I should 
use "serial" port, then what wiring you would suggest?
