Peter & Jakob, Thank you very much for your very clear explanation.
The /dev/ttyUSB0 is at the host and it does work, now it's clear for me how to make it visible from the chroot environment as well (and a bit of additional information on how qemu does work in user mode). Thanks! Pedro. -- Dr. Pedro E. Colla Adrogue - BA - Argentina "*El destino es el que baraja las cartas, pero nosotros los que las jugamos* ."
