I am having a difficult time trying to access a serial port on VirtualBox. My Guest OS is Windows XP and the host environment is Linux Ubuntu 10.04.

The serial modem device works perfectly开发者_如何转开发 in Ubuntu. I can communicate with it via cutecom or just sending plain echo messages to it like so:

echo "id" > /dev/ttyS2

Ubuntu Settings and config

I have added my user account to the following group: dialout and have set the serial using the following command: sudo setserial /dev/ttyS2 but still no luck when trying to access it in my Guest OS.

Heres the settings I use to configure the serial port in VirtualBox:

• Port Mode : Host Device
• Port Number : User - Defined (IRQ = 17, I/O Port = 0xEC00)
• Port/File Path : /dev/ttyS2

I have tried all the different port modes even disconnected but still no luck. I have consulted the manual aswell but nothing works. What could be wrong? Is it virtualbox or are my ubuntu settings configured incorrectly?

Please help

Thanks
