Logbook: Query entries (only with option 354)<br />
For complete interrogation of the logbook, first use the “RSLOO” command to read the oldest entry.<br />
Then use the “RSLOOC” command until an empty string (message terminators only) is received as<br />
an answer. The empty string means that there are no more entries.<br />
If only new logbook entries are to be read which have not yet been read out via the interface, use the<br />
“RSLOOC” command immediately.<br />
