dalla macchina ospite:
# echo atdt 12345 > /dev/ttyS0
# echo atdp 12345 > /dev/ttyS0
e le luci del modem visualizzano l'invio di dati
# cat /proc/ioports
03f8-03ff : serial
sulla macchina ospite esiste la porta
********************************************************
dalla macchina virtuale lennyhylafax:
# echo atdt 12345 > /dev/ttyS0
nessuna comunicazione.
# setserial /dev/ttyS0
/dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4
sulla macchina virtuale non la trova!!
Cosa impostare per accedere alla porta Com1 dove c'e' il modem?
Qualche suggerimento?
Grazie
ciao,
beppe
********************************************************
per configurarla ho usato:
http://www.deec.it/2009/09/15/installare-xen/
ma... finche' non ho trovato questa risposta:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=477525
(network-script 'network-route netdev=eth0')
la macchina virtuale partiva, ma si poteva accedere solo dalla macchina
ospite e non da tutta la rete.
