20 ;1) Create an entry in the HL7 APPLICATION PARAMETER file (771) called
21 ; 'PACS GATEWAY' and set ACTIVE/INACTIVE field to ACTIVE.
22 ;2) Create an entry in the HL7 NON-DHCP APPLICATION PARAMETER file (770)
23 ; called 'PACS GATEWAY' and set DHCP APPLICATION field to 'PACS GATEWAY'
24 ; (repoint to file 771).
