Are serial (RS-232) events with Mono 2.6 supported?

I've been trying to find out whether Mono 2.6 that will be coming with Unity 4.x supports serial events (RS-232). The current mono version doesn't support events, rather you need to use polling to snag the data coming in. Some details off the mono site:

I did find on the Unity compatibility page:

Class: SerialDataReceivedEventArgs (namespace System.IO.Ports, assembly System)

I've been trying to dig around and find out whether this means the new Mono version supports the events. Does anybody familiar with Mono 2.6 know whether events are supported now?

Thanks, Kyle
