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... -----Original Message----- From: nina jones <ddi@datadesigninc.com> To: MIDRANGE-L@midrange.com <MIDRANGE-L@midrange.com> Date: Wednesday, June 02, 1999 11:07 PM Subject: Re: Communication question >> >> Nina I do this for clients day in and day out with something that is >> much more critical that what GM is most likely sending, we do E-911 >> Automatic Number/Location Information interfaces.
