Will format and send a PDU using the specified command identifier and payload.

- (NSData*)sendCommand:(int)commandId :(NSData*)payload

Discussion

This method offers a way to do more with the class than is directly supported. This method takes a command identifier and a payload, which includes every required and optional field after the header, and will create the 16-byte header for it before sending it to the server. The response PDU is returned both in the PITrail and by this method.
