increasing number of xterms

[Stan Voket]

I'm running ISC 2.2 with their X 1.2 release.  I'd like to increase 
the number of xterm (or xpcterm) windows on my display.  I've 
increased the number of ptys from 16 to 24 by modifying 
/etc/conf/sdevice.d/pty and /etc/conf/node.d/pty.  I've added 
PTC_UNITS 16 8 24 to /etc/conf/cf.d/mtune and PTC_UNITS 24 to 
/etc/conf/cf.d/stune.  I rebuilt the kernal but cannot start any more 
xterms than before.  The error message I get is: X Toolkit Error: 
Can't Open display.  

What am I missing here?

Thanks in advance for the help! :-)
