* Command to load a splash screen to the VFDs.
|

|
* NOTE that this will be controlled by a key combination when

* the keyboard stuff works. For now the user has to enter a
|
||
|
|
* bitmap number (only VFD_TEST_LOGO is supported now - 16.10.2002).
|
||
|
|
* Added VFD_REMOTE_LOGO (same as VFD_TEST_LOGO but a different color)
|
||
|
|
* on 20.10.2002.
|
||
|
|
*
|
||
|
|
* This rather crudely requires that each bitmap be included as a
|
||
|
|
* header file.
