45b12307c695 Initial revision drewp parents: diff changeset	4 this is the only process to talk to the dmx hardware. other clients
45b12307c695 Initial revision drewp parents: diff changeset	5 can connect to this server and present dmx output, and this server
45b12307c695 Initial revision drewp parents: diff changeset	6 will max ('pile-on') all the client requests.
45b12307c695 Initial revision drewp parents: diff changeset	7
45b12307c695 Initial revision drewp parents: diff changeset	8 this server has a level display which is the final set of values that
45b12307c695 Initial revision drewp parents: diff changeset	9 goes to the hardware.
45b12307c695 Initial revision drewp parents: diff changeset	10
45b12307c695 Initial revision drewp parents: diff changeset	11 clients shall connect to the xmlrpc server and send:

45b12307c695 Initial revision drewp parents: diff changeset	15 a length-n list of 0..1 levels which will represent the channel
45b12307c695 Initial revision drewp parents: diff changeset	16 values for the n first dmx channels.
45b12307c695 Initial revision drewp parents: diff changeset	17
