The number of pending TCP/IP connection requests that the TCP/IP network software should hold while Mainframe Access is processing
the current connection request. Connection processing is typically handled very quickly and a small backlog of between 5 and
10 should be adequate for most installations. If you have an unusually high number of concurrent connection requests, some
end users might receive a connection reject message. Specify a positive integer value in the range 5 through 50.
