Design Guideline References:
Legacy Plug and Play Guidelines
Implemented as defined in Legacy Plug and Play Guidelines
Note: The following summarizes these legacy requirements, based on Legacy Plug and Play Guidelines:
-
Serial port meets device class specifications for its bus.
-
Legacy serial port is implemented as 16550A UART or equivalent and supports 115.2K baud.
-
Legacy serial port supports dynamic resource configuration.
-
Conflict resolution for legacy serial port ensures availability of at least one serial port.
-
Parallel port meets device class specifications for its bus.
-
Flexible resource configuration supported for each parallel port.
-
EPP support does not use restricted I/O addresses.
-
Compatibility, nibble mode, and extended capabilities port (ECP) protocols meet IEEE 1284-1994 specifications.
-
Port connectors meet IEEE 1284-I specifications, at minimum.
-
IEEE 1284 peripherals have Plug and Play device IDs.
-
Device identification string provides a Compatible ID key.
-
Daisy-chained parallel port device is Plug and Play capable.
