Re: Problem with TN5250

["John Aldrich" <jaldrich@xxxxxxxxxxxxxxxxxxx>]

Let me try it as a system-wide file and see if that works... if not, I'll
paste it here for comment. :D

tn5250 doesn't care what the permissions on the file are -- as long as 
the file exists in the user's home directory, and the user has read 
permission to the .tn5250rc file, it'll try to use it.

If you're trying to set a system-wide configuration, you need to omit 
the dot... so it'd be /etc/tn5250rc (or /usr/local/etc/tn5250rc) with no 
dot in the filename.
