	Mine also have the same permissions.  I was able to get an error
message from trying to execute xterm: 

xterm:no available ptys: no such file or directory

	I know this isn't true.  I have ptys listed in /etc/ttys and in /dev.
Do I need to add anything to /etc/ttys?  Here is what my ptys look like in

ttyp0 	none	network

	The rest under it are identical.  The tty that X comes up on is listed
as follows:

ttyE4	"/usr/libexec/getty Pc" 	vt220 off secure
	I'm using NetBSD 1.4.3.  Forgot to mention it in the original e-mail.
Not sure if that makes a difference.

of Course It Runs NetBSD
