Do you have any source code or reference design for DCD、DSR、DTR、RI on the SK board UART1 port ?

Hi Allan,

The signals DCD, DSR, DTR, RI on the Starter Kit board come out on pins which are either connected to the SD/MMC connector or the Ethernet PHY. You will have to do board modifications if you want to bring these signals out.
