My server program in vb6 successfully getting data from client ( Biochemistry analyser operating software). Data came is in duplicates i.e same data again send by client this happen when client give error. " LIS responce timed out". So I think when client is not getting server responce then send data again. Data send was like below
MSH|^~\&|Factory|Chemistry Analyzer|||20210430190330||ORU^R01|9|P|2.3.1||||0||ASCII|||

As I get above data. Then what responce I should send to client and How?
