I want to use UART hardware flow control with WP7608. How can I read RTS, CTS, DSR and DTR pin states. It means I want to check each pin is high or low.

Maybe you can run my sample application attached here. It will change the status of CTS every three seconds. It is working on my WP7608 FW R12. UART_Test1.rar (99.5 KB)
