Hi,

I'm trying to pipe the host's serial port /dev/ttyUSB0 to guest's (Windows XP) COM1 but I'm getting the following error:

Code: Select all

NamedPipe#0 failed to connect to local socket /dev/ttyUSB0.
VBox status code: -461 (VERR_NET_CONNECTION_REFUSED).

Result Code: 
0x80004005
Component: 
Console
Interface: 
IConsole {d5a1cbda-f5d7-4824-9afe-d640c94c7dcf}

Host is Arch Linux i686 with a 2.6.25 kernel.
Guest is Windows XP SP2.

I'm trying to map it with the following configuration:
Port number COM1.
Port mode Host Pipe.
Create pipe: disabled.
Port path: /dev/ttyUSB0

I'm running VirtualBox non-free 1.6.2 with "sudo" so permissions shouldn't be a problem. However, also tried to change them without success.

The serial port is in fact a USB to serial converter that seems to be properly detected by Linux:

Code: Select all

lrwxrwxrwx 1 root root 8 2008-06-23 21:30 /dev/ttyUSB0 -> tts/USB0
crw-rw---- 1 root uucp 188, 0 2008-06-23 21:30 /dev/tts/USB0

I am member of uucp group. Same results with /dev/tts/USB0.

Code: Select all

$ sudo setserial -a /dev/tts/USB0 
/dev/tts/USB0, Line 0, UART: unknown, Port: 0x0000, IRQ: 0
        Baud_base: 24000000, close_delay: 0, divisor: 0
        closing_wait: infinte
        Flags: spd_normal low_latency

I get no errors when issuing "echo" or "cat" on the device.

Any ideas? I'm completely stuck with this. Thanks in advance!

You have to use Host device as port mode to be able to use the physical serial device of your computer or a serial to usb converter

thanks!!! That let me boot the machine and install the COM1 port as a new device.

Now I'm getting errors when using the port with my application and experiencing the problem of long time shutdowns. I'll keep working on it.
