It definitely seems so. I tried inserting a printf statement directly before
and after
the call to fgets (and made sure the output was flushed, of course), and at the
beginning of the uci_handle_command function.

No, it does nothing like that.

Thanks! I have temporarily chosen the workaround of a global variable (because
I had
to release this version today), but I will of course return to the problem as

find the time.
