Thanks for the replies regarding problems with the tn3270 code. We are now using the V 4.1.1 code for the tn3270 emulator on sun worksations (sun3 and sun4). Everything seems to be working 100% except for one thing. I was puzzled since in the ANNOUNCE message describing fixes, this was mentioned as fixed... The problem is that when the user goes into an unformatted (empty) CICS screen the screen properly blanks but cpu consumption goes to 100% and the cursor moves rapidly through the right hand margin. The only way that we have been able to recover is to kill the process. Has anyone else experienced this kind of behavior or have suggestions on where in the code we should start to look? If possible I would appreciate responses by mail. I will format the answers/solutions/suggestions and post in the news group. !uunet!mhinfo!rwc Ralph Callaway P.S. One last question, does anyone have a fix to display the status line. Specifically, the users want to see the line showing things like the insert toggle mode.

I have also seen this problem, starting with version 4.1 of the tn3270 program. I hacked together a really gross fix for our site and contacted Greg Minshall about this problem. He replied that version 4.1.1 had fixed some problems with CICS screens. I obtained a copy of version 4.1.1, but it still didn't work correctly. I sent Greg copies of some network traces that show the traffic between the tn3270 host and the IBM system, in hopes that he might be able to duplicate the problem. I would like to see these problems fixed by Greg or someone in his group. My patchs seem to work, but I don't trust them for general distribution, since my understanding of how the tn3270 package works is incomplete. I would encourage anyone who is having similar problems either post about them here or send a note to Ralph (rwc@mhinfo.UUCP), who has volunteered to collect them and then post a summary to the net. Let me end by saying I do appreciate all the work that Greg Minshall has done to provide this valuable package. I just hope that we can get the last few quirks taken care of. -- Paul Lutt Domain: pwl@tc.fluke.COM Voice: +1 206 356 5059 UUCP: sun!fluke!pwl Snail: John Fluke Mfg. Co. / P.O.
