We often take protocol analyzer traces to diagnose performance problems
related to 5250 sessions.  The problems seem most likely related to issues
at the AS/400 and/or the client system rather than any kind of network
latency, but we still need the trace to prove which system is hanging and
when.  We, as network administrators, do not have detailed knowledge of all
the apps that are being access through 5250.  If we could re-create a 5250
screen and see it's contents at the time we observed the large delta time
in the trace, we would have a better idea of what the user was doing and
what applications were being accessed.

We usually use Network General Distributed Sniffer Servers to take traces.
These traces can be converted to tcpdump format and view through Ethereal.
Then, the data payloads could be extracted from a given TCP (Telnet) flow.
The display is tantalizingly like getting a view of the screen output (see
attachment 5250.txt).  But not really like looking at the actual screen
display, and no indication of what packet relates to what screen display

Any suggestions?

BTW, I installed your tn5250 on a Win2k system and tried to use the "debug"
option to view a trace. I got an error and, supposedly, generated a log
file.  If I knew where the log file  was created (it doe's not seem to be
in C:\Program Files\TN5250>) I would send it.
