* The ParallelPort component has the following component-specific (parmsParallel) properties:
|
||||||
|
*
|
||||||
|
* adapter: 1 (port 0x3BC), 2 (port 0x378), or 3 (port 0x278); 0 if not defined

*
|

|
* binding: name of a control (based on its "binding" attribute) to bind to this port's I/O
|
||||||
|
*
|
||||||
|
* In the future, we may support 'port' and 'irq' properties that allow the machine to define a
|
||||||
|
* non-standard parallel port configuration, instead of only our pre-defined 'adapter' configurations.
|
||||||
|
*
|
||||||
|
* NOTE: Since the XSL file defines 'adapter' as a number, not a string, there's no need to use
|
||||||
|
* parseInt(), and as an added benefit, we don't need to worry about whether a hex or decimal format
|
||||||
|
* was used.
|
||||||
|
*
|
||||||
|
* DOS typically names the Primary adapter "LPT1" and the Secondary adapter "LPT2", but I prefer
|
||||||
|
* to stick to adapter numbers, since not all operating systems follow those naming conventions.
