10774	more than two serial ports	BusyBoy		It seems that VirtualBox cannot support more than 2 serial ports per virtual machine. This limitation severly hampers the usefulness of VirtualBox for my applications. I run Suse 12.1 guest on Windows 7. The Windows 7 has 1 onboard serial port and two pci serial ports. I can only use 2 of the serial port at a time and tried manually changing the config file but it always defaults back to only 2 uarts or serial ports. Is there any way that you can specify more that 2 serial port for Virtualbox.... I tried using USB serial ports, but they are buggy and keep on re-enumirating and dissapearing from the guest. 	enhancement	closed	uart	VirtualBox 4.1.18	duplicate	more than 2 serial ports		Linux	Windows
