No, as we saw in the strace, the low-level read does not return. So it doesn't
matter how you intend to process the data on the higher levels ('rd' vs. 'read'
vs. 'line' or 'char').> and introducing delays at various points, but no luck so far. I'm going > to try to strace microcom and see what it does differently.

Yes, e.g (in File (make (while (char) (link @)))) But easier is (in File (till)) for a list of characters or (in File (till NIL T)) for a single long string. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
