Arguments:\r
\r
- This - TODO: add argument description\r
- CommandPacket - TODO: add argument description\r
- Event - TODO: add argument description\r
-\r
+ This - Protocol instance pointer.\r
+ Packet - The SCSI request packet to send to the SCSI \r

+ Event - If the SCSI bus where the SCSI device is attached\r
+ does not support non-blocking I/O, then Event is \r
+ ignored, and blocking I/O is performed. \r
