Ticket #9109 (new enhancement)

There are only 2 serial ports available per virtual machine

Description

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 virtualized fax servers that are portable across OSs and connect to external modems through mapped serial ports. For a typical 4 or 8 line fax board, this means I cannot scale the application to fully utilize the available hardware. As far as I know only VMWare supports unlimited serial ports per VM among the competition.

Hello,

has anyone found any workaround ? I'm using VirtualBox as fax server too, and the only way I found is to install a second virtual machine to connect additionnal modems...

I have modems and can help for testing.
