8.5.6 Device Type

A device represents a single display on which frames exist. Normally, there is only one device object, but there may be more than one if SXEmacs is being run on a multi-headed display (e.g. an X server with attached color and mono screens) or if SXEmacs is simultaneously driving frames attached to different consoles, e.g. an X display and a TTY connection.

Devices do not have a read syntax. They print in hash notation, giving the device’s type, connection name, and a unique number assigned at the time the device was created.
