It also contains the following functions. + + +.. function:: comports() + + :return: an iterable. + + The function returns an iterable that yields tuples of three strings: + + - port name as it can be passed to :class:`serial.Serial` or + :func:`serial.serial_for_url` + - description in human readable form + - sort of hardware ID. E.g. may contain VID:PID of USB-serial adapters. + + Items are returned in no particular order. It may make sense to sort the + items. Also note that the reported strings are different across platforms + and operating systems, even for the same device. + + .. note:: Support is limited to a number of operating systems.

However it may inherit these features from the terminal it is run. +For example on GNU/Linux running from an xterm it will support the escape +sequences of the xterm.
