Most drawing devices, such as tablets, touchscreens, etc., are designed to be used with a computer. Most computers are starting to use USB ports as opposed to the DB-9 RS-232 port, therefore RS-232 DB-9 serial devices are becoming more and more obsolete, as the USB devices are starting to become standard.
New Pointmakers will support both USB and RS-232 devices, and may eventually move to only USB.
