Stream Reporting (*S)
The *S command causes the control unit to enter the Stream reporting
mode. In Stream reporting mode, the control unit sends mouse data
reports continuously. The host computer may have to keep up with an
information flow of 50 reports per second.
Diagnostics (*<enq>)
The *<enq> command causes the control unit to return a two-byte
response containing diagnostic information (see Table 6-4).

Where in Table 6-4,
TO = Control Unit test
T1 = Processor test
T2 = EPROM checksum test
T3 = RAM test
T4 = Transmitter test
T5 = Receiver test
T6 = Serial Port test
T7 = EEPROM test
T8 = Reserved
T9 = Reserved
TA = Reserved
TB = Reserved
In the above test results, a "0" indicates that the test failed. A "1"
indicates that the test passed. Therefore, a BF 3F (hex) represents an "All
Pass" result. Any other response indicates that at least one test failed.
