Read RXD line in RS232

[wilkxt]

Hello

I use WriteFile etc. function to access COM port in PC. I can read DSR,CTS linie when I use GetCommModemStatus() but not RxD. Is posible to read state RxD linie in this port?


regards

The GetCommModemStatus function retrieves modem control-register values.
But RXD (Receive Data) is

The data signal to the PC. What the user sees from the remote host.

You have to use ::ReadFile API to read this data. See Serial Communications in Win32
