DGHTRTX ;ALB/JRC - Home Telehealth HL7 Message Monitoring Routine ;10 January 2005 ; 9/14/06 12:52pm
 ;;5.3;Registration;**644**;Aug 13, 1993;Build 11
 ;
 ;This routine when tasked will run at predetermined time intervals
 ;and check to see if there are any HTH HL7 messages that have not
 ;received an application acknowledgment. If it finds messages that
 ;have not received AAs, it will retransmit the HL7 messages up to the
 ;number of times defined in the "DG HTH # OF RETRANSMITS" parameter.
 ;If no AA is received after the 5th try an alert is sent to the
 ;DGHTERR mailgroup. After the 5th try an extended wait time is used
 ;(12 hours) and the process starts a new.
