Yes, I'm tty group: |
| 25 |
tty lp wheel mail cron audio cdrom postgres cdrw usb users scanner vboxusers |
| 26 |
|
| 27 |
in addition I have try to change the permission to: |
| 28 |
chmod 0666 /dev/ttyS0 |
| 29 |
|
| 30 |
but it makes no difference, when starting virtualbox xp I'm still getting the error: |
| 31 |
NamedPipe#0 failed to connect to local socket /dev/ttyS0 (VERR_NET_CONNECTION_REFUSED). |
