The TransmitCommChar function transmits a specified character ahead of any pending data in the output buffer of the specified communications device.
BOOL TransmitCommChar(
HANDLE hFile, |
// handle of communications device |
char cChar |
// character to transmit |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The TransmitCommChar function is useful for sending an interrupt character (such as a CTRL+C) to a host system.
If the device is not transmitting, TransmitCommChar cannot be called repeatedly. Once TransmitCommChar places a character in the output buffer, the character must be transmitted before the function can be called again. If the previous character has not yet been sent, TransmitCommChar returns an error.
Character transmission is subject to normal flow control and handshaking. This function can only be called synchronously.
