thanks for the answers.

/* transmit eth-messages to the specific com port (is working) */
unsigned char* buffer=new unsigned char[400];
memcpy((void *)&buffer[0], (void *)&ptr->Data[0], 400);
m_Ports[number].m_serialWriteThread-

PostThreadMessageA(UWM_SEND_DATA2, (WPARAM)&buffer, 400);

The &buffer is the address of the pointer, not the address of the buffer.
Use buffer, not &buffer

void CSerialWriter::OnSendData(WPARAM wParam, LPARAM lParam)
{
unsigned char * schar = (unsigned char *)wParam;
UINT length = strlen((const char *)wParam); //<- 3 instead of 400

BOOL ok = ::WriteFile(parms->hCom,(unsigned char
*)schar,lParam,&bytesWritten,&ovl);

Why write 400 bytes when strlen has determined there are only 3 bytes
received?

//....

delete [] schar;
}

How can I delete the unsigned char array at the end of the
OnSendData() function?

delete [] schar is the correct way to delete the buffer.
