I read:
Anyone now if it existe an external to be able to drive the 5DT = dataglove ?
there is a [serialctl] object in ggee (http://gige.xdv.org/pd/ggee) that might get you started.
another question : what about link between VRML et PD ?
don't know much about it but there was a thread about this here a while ago: http://iem.kug.ac.at/mailinglists/pd-list/2004-05/022149.html
