Close https://github.com/johnpaulett/python-hl7/issues/41 As pointed out in the issue, send does not guarantee that all of the data is sent. We have observed this behavior in production and using sendall fixes...

use socket.sendall() instead of socket.send()

In a big project I currently encounter the fact, that another software receives just a partial MLLP message. While debugging this issue I looked at the code of https://github.com/johnpaulett/python-hl7/blob/main/hl7/client.py Though...

read_stream() - message longer than RECV_BUFFER raises MLLPException('buffer not terminated...')

3

The read_stream function reads just one chunk of data that must be at most RECV_BUFFER bytes long. This breaks when a message is longer than RECV_BUFFER. The fix is keeping...

MLLP client doesn't receive full ack response when expected

Backslash is swallowed when unescaping sequence like `\E\R\`

1

See this example piece of code: ```python msg = hl7.Message(separator="\r", sequence=[["MSH", "^~\\&"]]) unescaped = msg.unescape("\\E\\R\\") ``` `unescaped` should be `\R\` because: * the first `\E\` becomes a literal `\` *...

When instantiating a `Message`, a `sequence` can be passed to the constructor, *but* this sequence must be formed in a very specific way, else the `Message` instance is functionally unusable...
