I'm using zedboard with Axi 16550 Uart. I want to use this uart in half duplex mode, I'm using Linux from
Analog devices, hw design for adv7511 xcomm branch. How can I control the transceiver's Driver enable and receiver enable pins with this uart?
When i look at the RTS and DTR with hardware flow control enable, these pins deassert after very long time the data is transmitted. Can i make a signal just after the stop bit?
If I can read the THRE bit in IIR register in user space, I can set the DTR or RTS in the user space, but how can i read (poll) this bit in user space?
