TCP/IP Disconnected Sessions with Rumba

Happy New Year all
At work on our big boxs we are using Rumba Office/95 connected via TCP/IP
as a term emulator.I am having a problem where out of the blue the Rumba
Session gets disconnected (you get a blank screen-no sign on).Upon queri
the AS/400 my session still shows varied on.
I was wondering if I can have a list of commands to check any suggested 
parameters on a "Virtual Controller".
Using Netsoft Elite via SNA does not give us any problems only TCP/IP !!

I have been on this list for the past year and a half but have mostly
worked on HLLAPI and Client Server
programs via VB so I do not know much aboubt the AS/400 internal working
despite having a model200
and some old E20s at home
