List members determined that my problem with being disconnected when using
a 60 x 160 size 3270 screen was that my DATABUFFERPOOLSIZE was too small.
My PROFILE TCPIP had a DATABUFFERPOOLSIZE of 8K so I thought that 9K
would work but it didn't. I found a message in the TCPIP console log
that my DATABUFFERPOOLSIZE was invalid. Well after RTFM I found that
the buffer size must be a multiple of 4K.
So I tried 12K and my problem was solved
My thanks to the list members and IBMer Bill Moy.
