Re: Communication question

Nina,

        Yes, look at the "Asynchronous Communications Programmer's Guide"
SC21-9592  for some direction and help in getting the AS/400 to connect to
the link.

        BUT, the reason I used the approach I have is that ASYNC over a data
comm link can be a real issue with dropped or mal-formed bytes, and timimg
issues to the ASYNC controller if you have an ACK/NAK protocol.  By puting a
device at the interface and using a more robust protocol over the
network/DDS connection you will have MUCH less gray hair in the long run.

        You do have lot's of good options from list members.

        Good Luck,
        JMS...
