In-Process Acknowledgment Response Message Conventions
Each command received by the SSU-2000 with a valid tid generates a response
when the terminating semicolon is received, followed by an output response
message or the output response.
The SSU-2000 sends the in-process acknowledgment (IP) only if it is unable to
respond to the command within two seconds. The requested response is then sent
in full when the SSU-2000 data is available.
The in-process acknowledgment response always begins with a carriage return and
two line feed characters, and ends with the header line containing the source
identifier (sid), defined below, and the date^time stamp.
The format for the IP acknowledgment message is:
<cr lf lf>
^^^sid^date^time <cr lf>
IP^ctag <cr lf>
<
where:
(Source Identifier) is the returned ID, and is the same as the tid in the input
sid
command message to which the IP acknowledgment is responding.
