Thanks for pointing out! If thinking about it, it works bacause I
explicitly added code to the cc65 C library:

When chars are coming in through COUT then DOS 3.3 checks the zeropage
location PROMPT to see if you're in the BASIC interpreter intermediate
mode or running a BASIC program. The cc65 C library changes the PROMPT
in the same way (to make DOS 3.3 understand that it shouldn't react on
"CATALOG" but only on "<Ctrl-D>CATALOG").

Seems to work nicely after all :-)

And maybe worth mentioning: On the Apple2 the cc65 C library makes all
stdio I/O from/to stdin/stdout/stderr go through the standard BASIC
I/O hooks (therefore the printf() above works). On the other hand
conio I/O is directly from/to the hardware. But conio still
uses/updates the usual zeropage locations (even the less common for
"windows") so you can easily mix both kinds of screen output...

Best, Oliver
