This package can be distributed to any one who has a license for this product. +----------------------------------------------------------------------+ PREREQUISITES : IBM Communications Server for Windows NT version 5.01 PROBLEMS FIXED: APAR Number Description JR12112 1) Clients hung using typeahead feature. This was due to data from the client that the TN3270E Server had queued up waiting for direction being sent after the host sent query reply data. The host application was set up to not accept anything other than the response to the query reply data. TN3270E Server was changed to implement a 15 second timer to detect hung connections and send a SIGNAL RU if data is waiting to go inbound to the host. 2) Code changes were made to correct buffer lengths on TN3270E Server display. This is to prevent traps during display. JR11906 TN3270E Server will only discard LU-LU data received from the client if the session is not in LU-LU state. Before this change, clients can end up in a hang condition due to the fact that the server discarded client data. The server was discarding the data due to the fact that the client was presenting data to the server when the server was waiting for a response to prior data posted to the client. JR11798 SNA CLEAR RU was not being handled properly by the TN3270E Server. This results in clients getting disconnected (bounced back to the USSMSG010 screen) due to RUI_WRITE errors.
