Health Language 7 is a protocol for sending information between health computing systems. HL7 messages are sent as text through a TCP/IP connection. Each Message consists of several lines, each of which start with a three letter name.
VistA has several HL7 files that specify how messages are transmitted and received:
| File Number | File Name | Description |
