[ 37 ] PS/2 Keyboard Test
[Function]
Tests whether the interface operates correctly.
An echo command is transmitted to PS/2 interface keyboard to see if there is a correct echo
response.
It must be a command-response communication, and one transmission is performed per test.
If there is an error in data reception or a transmission time-out, the test is repeated the specified
number of times. The results are displayed at each retry and, then, printed out when the test ends.
When retry is set to repeat indefinitely, the test is repeated indefinitely.
Executing the test turns on the power to PS/2 and ending the test turns the power OFF.
