Routine Description:
|
||
|
|
|
||
|
|
This routine sends a command or data byte to the keyboard
|
||
|
|
in polling mode. It waits for acknowledgment and resends
|
||
|
|
the command/data if WaitForACK is true.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
Context - Function specific context
|
||
|
|
|
||
|
|
PortType - If PortTypeCommand, send the byte to the command register,
|
||
|
|
otherwise send it to the data register.
|
||
|
|
|
||
|
|
WaitForACK - If true, wait for an ACK back from the hardware.
|
||
|
|
|
||
|
|
AckDeviceType - Indicates which device we expect to get the ACK back
|
||
|
|
from.
|
||
|
|
|
||
|
|
Value - The byte to send to the hardware.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
STATUS_IO_TIMEOUT - The hardware was not ready for input or did not
|
||
|
|
respond.
|
||
|
|
|
||
|
|
STATUS_SUCCESS - The byte was successfully sent to the hardware.
