Virtualbox Serial Port Step-by-Step


Can anyone guide on how to setup the serial port to work if using VirtualBox.

My host is Windows Server 2008 and My guest is debian.

I just need a simple thing...

I need the Serial port to work on the V-machine (debian) when so I can collect the PBX data..

Well, VirtualBox can't give guest OS access to the host system's serial port. I believe VirtualBox can give the guest access to a USB port, so maybe a USB to RS232 adapter could work.

EDIT: I stand corrected, I thought those were virtual serial ports, I didn't realize they could be mapped to physical ones.

What symptoms do you have? Any clues to what went wrong?

It's pretty straight forward, that wordpress article shows all the steps that are required. I have my VirtualBox set up this way, exporting COM1 from my WinXP machine into the Ubuntu VM. kermit has no trouble communicating with my Gumstix board through a null modem cable on this port with it set up like this.

I wish it was that easy my friend!

I have tried all the options with the serial but it's still not working...

Ok.. could you please guide on this..

My host is WINDOWS SERVER 2008 and my guest is Debian Squeeze.

1. I have gone to the Serial Port Setting in VirtualBox.
2. Enabled Serial Port is checked.
3. Port Number : COM1
4. Port mode is : Host Pipe.
5. (Create Pipe) is checked.
6. Port File/Path: \\.\pipe\COM1

In Debian
7. I started Putty.
8. Choosed Serial Mode
9. In Serial line : \\.\pipe\COM1
10. In Speed: I tried 9600 and 115200

BUT...

I am getting the following error when I click Open in Putty to open the connect:

Quote:
Unable to open connection to:
Unable to open serial port

Thanks,
Jassim

Where did you get those config parameters? As described in the wordpress article, I have mine set to:

Port Number: COM1
Port Mode: Host Device
Port Path: COM1

Then in linux:
kermit -l /dev/ttyS0

I usually use kermit, but minicom works as well, and I see no reason why putty, or any other terminal client wouldn't work. You just need to use the /dev/ttyS0 device for COM1.

Then you don't have Kermit installed.

There are many different clients you can use, Kermit is just my preference. Kermit, minicom, putty, whatever you choose, you just need to connect to /dev/ttyS0.
