Bits per second can be 110 and go up to 256000, by default 57600 is selected.

Databits

File Configuration field:

nDatabits

Description:

Databits defines that how many bits you want to send and receive to the communication port.

  3. 2 stop bits

DTR Control Flow

File Configuration field:

nDtsControl

Description:

DTR (data-terminal-ready) flow control. This member can be one of the following values:

  1. DTR_CONTROL_DISABLE - Disables the DTR line when the device is opened and leaves it disabled.

  2. DTR_CONTROL_ENABLE - Enables the DTR line when the device is opened and leaves it on.

  3. DTR_CONTROL_HANDSHAKE - Enables DTR handshaking.

RTS Control Flow

File Configuration field:

nRtsControl

Description:

RTS (request-to-send) flow control. This member can be one of the following values:

  1. RTS_CONTROL_DISABLE - Disables the RTS line when the device is opened and leaves it disabled.

  2. RTS_CONTROL_ENABLE - Enables the RTS line when the device is opened and leaves it on.

  3. RTS_CONTROL_HANDSHAKE - Enables RTS handshaking. The driver raises the RTS line when the “type-ahead” (input) buffer is less than one-half full and lowers the RTS line when the buffer is more than three-quarters full.

  4. RTS_CONTROL_TOGGLE - Specifies that the RTS line will be high if bytes are available for transmission. After all buffered bytes have been sent, the RTS line will be low.

Message to Send

File Configuration field:

szMessage

Description:

This is the message that is to be sent to the device. You can enter text plainly and you can also include all properties from the current event. For example, if you have a serial audit printer and you would just plainly like to log arrived messages to that printer, you could use the string “%msg%%$CRLF%” to write the actual message arrived plus a CRLF (line feed) sequence to the printer.

Please note that the message content of the Message field can now be configured. event properties are described in the property replacer section.
