A little grepping in the source finds this code that triggered the "Unknown command" error is in src/hal/utils/halcmd.c:

That code is part of the command line parsing from halcmd, seems unlikely.
There are some others, if you do a case insensitive search, but equally unlikely

I wouldn't be surprised to find that all HAL commands go through halcmd.
Why have two HAL parsers?

I wouldn't be surprised to find that all HAL commands go through halcmd.

I had thought of that but could not find any calls to halcmd within the /src except from minor uses by halsh.c and halmodule.cc

The function parse_cmd1(..) in which this error message occurs, is only referenced inside halcmd.c.
halcmd_parse_line(..) which uses parse_cmd1() looks a likely candidate, but is also only referenced inside halcmd.

The source code is a spaghetti bush, but I haven't found a strand which leads there yet :blink:
