3.3 Writing your own Application in Visual C++
This example illustrates the access to a com port of a handheld. A handheld normally
sets the serial port of the CF slot to 4, 5, or 6.
// set the appropriate com port
CString m_Serial = "com4";
bool m_contReceiveMode = false;
HANDLE hComm;
// Open communication
hComm = CreateFile(m_Serial.GetBuffer(), GENERIC_READ |
GENERIC_WRITE, 0, NULL, OPEN_EXISTING,
FILE_FLAG_WRITE_THROUGH, NULL);
if (hComm == INVALID_HANDLE_VALUE)
{
printf("error\n");
hComm = NULL;
}
else
{
COMMTIMEOUTS noblock;
