Hi,
You have connected the LED between transmit data (TD) and ground (SG). Is is your intention to show when data is being transmitted or do you just want to turn an LED on and off?

If it's the latter then it would be better to connect the LED to one of the control lines, e.g. data terminal ready (DTR) or request to send (RTS), and ground. These lines can be toggled or or off via the SerialPort class.

The timer tick code would be e.g.
port.DtrEnable = !port.DtrEnable;

Alan.
