VirtualBox and sharing serial port

[catfishhoward]

I'm new to this but I have a Window xp 32-bit and I just made another vertualbox of the same Window xp 32-bit. I have to have a PCI-e serial port for a certain program to work which it works on my host but I can figure out how to get the virtual copy to recognize the port?

Shutdown your XP. On the second picture - enable COM1 (on virtual machine) and route it to actual serial port on the host (it might be COM1, COM5 or COM15).
