|
|
A successful receive of a transfer packet will result in a Result Acknowledgement being written
|
|
with the value `[]byte(byte(1))` in the `Response` field.
|
|
|
|
An unsuccessful receive of a transfer packet will result in an Error Acknowledgement being written
|
|
with the error message in the `Response` field.
