I have an application that run's on winNT and requires the APCI-7500 card (a 4-multiport serial card), so I've installed the winNT thru virtualbox, but as i try to configure the serial ports I notice that virtualbox shows only 2 serial ports, only 2 tabs in the ports configuration section.
How can I add the other 2 ports and configure them.
My host is ubuntu 11.04
My guest is winNT
My virtualbox version is 4.0.4_OSEr70112
I'll appreciate any help.
Thanks in advance.
I've followed these threads but still get no light in this issue
