| 17 | To use this library the module "pcicc32.o" have to be installed. There must be also a |
||
| 18 | node which points with ist major number to the module and its minor number must equal |
||
| 19 | the CC32 module number (Jumper J301 to J304). |
||
| 20 | |||
| 21 | first steps derived from the LINUX pcicc32 library AR 16.03.2000 |
||
| 22 | added buffer, UNTIL_NOT_Q and AUTOREAD functionality AR 17.03.2001 |
||
| 23 | added interrupt handling (NT + 2000 only) AR 08.06.2002 |
