Re: Serial thread continued

Below is my Serial thread:
---------------------------------------------------------------------

UINT SerialThread( LPVOID Param ) //Thread to monitor serial activity
{
  char ed[10]; //for testing on=

  unsigned char chread;
  DWORD dwRead;
  DWORD dwEventMask;

  if(!SetCommMask(hCom, EV_RXCHAR))
    AfxMessageBox("Error setting ComMask");

  if(WaitCommEvent(hCom, &dwEventMask, NULL)){
    ReadFile (hCom, &chread, 1, &dwRead, NULL);
    _itoa(chread, ed, 16); //for testing only
    AfxMessageBox(ed); //for testing only
  }
  return TRUE;

}

---------------------------------------------------------------------

hCom is the comport handle.
chread is the byte returned.

The following 2 lines are only there to see what char was returned.
They will NOT be in the final routine.....

    _itoa(chread, ed, 16);
    AfxMessageBox(ed);

The routine does respond and the messagebox shows the byte that came
in.
BUT, the byte is not what was sent!

Any ideas??
