uart st16c550 rs485
hi
for RS485 half duplex or multidrop systems, we have to disable the TX driver when we are not transmitting. Normally it is done by the DTR or RTS signal from the UART, controlling the buffer within the transceiver.
Is there a way to generate this automatically by the UART without any software intervention? is it in the standard PC 16550 UART?
