Are you sure your expansion board is based on the "classical" UART (8250 or 16550) ? Many add-on cards require specific modules. This will not work on dom0 if the serial port is already shared, but you can try it when no domU is running : $ for x in 0 1 2 3 4 ; do setserial /dev/ttyS$x ; done /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3 /dev/ttyS4: No such file or directory # (this machine has only one physical port) My 2 cents, -- Philippe _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
