How would I go about connecting a UART comms port from a micro (TTL) to the m-bus? What's involved? do I need to use a Max323??

there are some options for you
see HERE (http://www.nokia-unlocking.pwp.blueyonder.co.uk/resource/) for cable schematics and phone pinouts.

you can also buy pre made data cables for next to nothing these days..
