Andy,

The polling application does work against the AS400 DB2 database.
As the server has 40 modems connected to it , I would have thought that only
40 concurrent connections could be made.
If each modem opened a single connection , can I reasonably say that this
modem can make 200 connections before the QZDASOINIT job is ended and
another takes its place. (is that basically how it should work?)
