The SERIALKEYS structure contains information about the SerialKeys accessibility feature, which interprets data from a communication aid attached to a serial port as commands causing the system to simulate keyboard and mouse input.
typedef struct tagSERIALKEYS { // sk DWORD cbSize; DWORD dwFlags; LPSTR lpszActivePort; LPSTR lpszPort; DWORD iBaudRate; DWORD iPortState; } SERIALKEYS, FAR* LPSERIALKEYS;
Value |
Meaning |
SERKF_ACTIVE |
The SerialKeys feature is currently receiving input on the serial port specified by lpszPort. |
SERKF_AVAILABLE |
The SerialKeys feature is available. |
SERKF_INDICATOR |
A visual indicator is displayed when the SerialKeys feature is on. This value is not currently used and is ignored. |
SERKF_SERIALKEYSON |
The SerialKeys feature is on. |
Value |
Meaning |
0 |
All input on this port is ignored by the SerialKeys feature. |
1 |
Input on this port is watched for SerialKeys activation sequences when no other application has the port open. |
2 |
All input on this port is treated as SerialKeys commands. |
An application uses this structure when calling the SystemParametersInfo function with the SPI_GETSERIALKEYS or SPI_SETSERIALKEYS value. When using SPI_GETSERIALKEYS, an application must specify the cbSize, lpszActivePort, and lpszPort members of the SERIALKEYS structure; the SystemParametersInfo function fills the remaining members. An application must specify all structure members when using the SPI_SETSERIALKEYS value.
