RE: 5250 Documentation

Sameer,

I have written a telnet 3270 and 5250 test service, which can be very usefully for your development.
It's a NT service, which can handle both tn3270 and tn5250 clients. The reply from the service is
different 3270 or 5250 screen images with most of the attributes needed. The service has three
different ports for connections. One is a normal reply mode port, one is a slow mode reply port
and the other is a stress test (performance) connection port. More information and download in the
services section at www.nexit.com It can also be downloaded from the test center at www.tn3270.com

Regards,
Hans Erik
