* tty: Blackin CTS/RTSSonic Zhang2009-04-071-3/+6
| | | | | | | | | | | | | | | Both software emulated and hardware based CTS and RTS are enabled in serial driver. The CTS RTS PIN connection on BF548 UART port is defined as a modem device not as a host device. In order to test it under Linux, please nake a cross UART cable to exchange CTS and RTS signal.
