Request for assistance

[Mark Glassberg]

I have a device file authorization problem.  I'm using expect version 5.12.0.
When I tell expect to "spawn telnet", I get the following: 
     pty master (/dev/ptysf) is locked...skipping
     too many programs spawned? - out of ptys
         while executing
     "spawn telnet"

I cannot find any lock files for /dev/ptysf and I've tried "chmod 777 /dev
/pty*", but I still get the same error message.  I do not, however, have 
any problem when logged in as root.  Any suggestions would be most welcome.
