Re: IBM 5250 emulation

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

Thanks Rob, and thanks to everyone who replied. My going in position is 
that the 5250 data stream has been stable for about 50 years.  That 
being said, I think we need to review secure Telnet, but that's another 
project for another day.  We have no direct Telnet access outside the 
firewall so I'm less concerned, but nowadays everything is a threat vector.

Anyway, thanks again to everyone.  I appreciate it!
