am a newbie to Beaglebone black. I want to establish full UART with hardware flow control using RTS,CTS,DTR,DSR,DCD and RI on UART1 so that I could establish a full modem handshaking. Can you suggest how should I proceed? I have gone through following http://blog.pignology.net/2013/05/getting-uart2-devttyo1-working-on.html
to enable UART1 Tx and Rx. Now can you help me further about how to enable RTS,CTS,DTR,DSR,DCD and RI.
