bitseeker:
Sure thing. Thanks for chiming in, PeLa. We can't all know about every industry's use cases.

RoGeorge:
NEW BUG (Software 00.04.04.SP3, Board 0.1.1): When a bad SCPI command is followed by at least one other command, then querying the error queue using ":SYST:ERR?" will lead to unresponsive (hang) SCPI over TCP/IP (LXI) until the next power cycle.
Note: This will not happen for any bad command, so far I found that commands that make the oscilloscope to display "Function Limited!" or "Invalid Input!" will trigger this kind of bug. I didn't test it for USB/SCPI commands.

Steps to reproduce:
1. Connect a Rigol DS1054Z to LAN, then start Netcat by typing in a terminal:
nc 192.168.1.3 5555

3. In the NetCat, type
:WAV:STAR 0

4. Now type at least one more SCPI command, good or bad, for example
:WAV:STAR 1

5. SCPI apparently is still working, until you type:
:SYST:ERR?

6. Now the oscilloscope won't respond to any other SCPI command, and it won't accept new TCP connections until the next power cycle.

Rigol, please fix it.
 :-BROKE



Example

--- Code: ---:WAV:MODE:NORM
:syst:err?
-113,"Undefined header; keyword cannot be found"

:WAV:MODE NORM
:syst:err?
0,"No error"

:WAV:MODE STAR 1201
:syst:err?
-220,"Parameter error"
:syst:err?
0,"No error"

--- End code ---
So far all good, as expected.

Now, try this:

--- Code: ---:WAV:STAR 1201
:WAV:STAR 120
:syst:err?

--- End code ---
That's it, after the last ':SYST:ERR?' SCPI hangs, and no other SCPI commands will work until the next power on.

Later edit:
It would be useful if anybody else can reproduce this, please. Does your DS1000Z hangs, too?

zbyr:
Yup. Bug also exist in SCPI with USB connection.

RoGeorge:
Thank you for testing it.

Karel:
Regarding the scpi command bug, is somebody going to report it to Rigol and post the date of reporting and contact details (Rigol NA/Europe/etc, name of Rigol contact person) here?
