APRSIS32 and APRS-SCS

This evening whilst the XYL is out and about I thought I'd try and follow something that Julian, G4ILO had done with a software tnc call APRS-SCS connected up to APRSIS. His original post is here and gives all the right places to go to get the software. Well getting the software is the easy part, getting APRS-SCS to decode the few packets I heard locally is ok. APRSIS32 displays the packets. But can I get APRSIS to transmit through APRS-SCS (Too many APRS's here I think)? Not yet. This is going to work if it's the last thing I do before I go to bed early in a sulk ;-)
