193 The keyboard controller will perform a simple self-test on power-up to detect
195 keys. Any keys down at power-up are presumed to be stuck, and their BREAK

232 mode and parameter settings. It does not affect the time-of-day clock.
233 The RESET command or function causes the ikbd to perform a simple self-test.
234 If the test is successful, the ikbd will send the code of 0xF0 within 300mS
235 of receipt of the RESET command (or the end of the break, or power-up). The
236 ikbd will then scan the key matrix for any stuck (closed) keys. Any keys found
