[logex]

Hi all:

I'd like to know if there is such a thing (public domain),
as tn3270 but, what i need to emulate is a 5250 and/or
5251 terminal for an IBM System 36.

Can you tell me where can i get such software.? I am planning 
to implement it on a Xenix system or NCR Tower Unix system.

I'd appreciuate your help, thanks in advance.!!
