Currently the pong device does the following: - on PONG_WRITE requests: read the CCW buffer, expect a string with an integer in the buffer. store the integer in a variable initialy initialized to zero. - on PONG_READ requests: Store the value of the variable + 1 as a string in a buffer send back the buffer - defines a Control Unit property of type CCW_PONG_CU_TYPE for the guest to recognize the PONG device when using a SENSE_ID command.
