Thanks for the quick response...

The TN3270 connection is not necessary as I am going through a Data PBX
and Asynchronous Emulation Adapters (AEA's) on my front end to the mainframes,
which will give me VTxxx emulation by default. 

I thought about what's involved in writing this hack myself, but it also 
seems that the Comshare software is using some beast called "OS286" which 
I hear (rumor) does some switching in and out of protected mode so as to get
large tracts of virtual memory, thus further complicating my problem.

The really annoying thing is that the package has hooks to use some other 
API's, some of which allow the specification of port addresses...I can't 
imagine writing stuff to delete someone else's 3270 screen control codes
from the data stream, however.

I've heard an answer from the most definitive source I know (that's you 
James!), so now I'll fall on the net: If ANYONE out there has any experience
in doing LAN configuration with Comshare's COMMANDER product, PLEASE drop me
a note. I suspect that they may have done this before, and are just not 
documenting it, based on their price/time estimates to provide this
functionality.


P.S. Will the glorious TN released in 2.05 work under the 2.04 kernel???

Thanks to all in advance,
