@SetNTComPortEventMask

Only for Engine under Windows!

Resets the current event mask for the COM port identified by OSCOMHANDLE OSCOMHANDLE1. A subsequent @WaitNTComPortEventMask can then be used to wait for the occurrence of an event.

FN MASK2:
Bit   HEX   C symbol   Meaning
1      0001   EV_RXCHAR   A character was received and added to buffer
2      0002   EV_RXFLAG   An event character was received
3      0004   EV_TXEMPTY   The last character in output buffer was sent
4      0008   EV_CTS   The CTS signal changed state
5      0010   EV_DSR   The DSR signal changed state
6      0020   EV_RLSD   A RLSD (DCD) signal changed state
7      0040   EV_BREAK   A break was detected on input
8      0080   EV_ERR   A line-status error has occurred
9      0100   EV_RING   A ring indicator was detected

Example: @SetNTComPortEventMask(OSCOMHANDLE1);

OSCOMHANDLE1:=@OpenNTComPort("COM1");
@SetNTComPortEventMask(OSCOMHANDLE1;256);
@WaitNTComPortEvent(OSCOMHANDLE1);
@LogReport("Ring-detect: "+@Text(@Now));
@OSCOMHANDLE1:=@CloseNTComPort(OSCOMHANDLE1);

Opens a COM port, waits until ringing is signaled, outputs the time, and then closes the port again.
