They supposedly have complete emulation of VT320 and VT420.  However, in 
practice, I've found that on many OS's codes that work fine on a real 
VT420 don't work well at all on a VT520.  It's been quite a while since 
I've done it, but if you're interested, I can hook my VT520 up again and 
work out which ones were pissing me off so much again.
