Make sure it has an FTDI chipset in it. FTDI devices have a unique serial number so that the port is uniquely identifiable no matter where it is plugged in to the USB tree.
When you're setting up don't use /dev/ttyUSB3, use /dev/serial/by-id/usb-FTDI_USB_Fast_Serial_Adapter_FTTOYUBC-if00-port0 Which is both unique and repeatable - no matter where you plug the device in, it will show up with this name (FTTOYUBC is the serial number of this particular chip). I've purchased a 16 port rack mount version from this outfit at work: https://www.serialgear.com I've got one of these at home: http://www.digikey.com/product-detail/en/USB-COM232-PLUS4/768-1034-ND/2139296 but a pretty obvious downside is that it's a bare board, no enclosure. -Jason kg4wsv _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
