Interfacing with Opus MCU500

[riddelln]

Hi - I'm a newbie to the forum and have found it really useful and informative.  I've been set a challenge.  I need to interface LinuxMCE with an Opus MCU500 unit.  In the manual it states that the unit has an RS232 expansion slot - however it also states that allowing external control is a future feature.  Has anyone ever tried to do this?
