regards:
by the way could I ask a question,could I simply use the "RTS line" to control RS485 half duplex mode?
and I ask a question. and when I am using RS485 FULL duplex (RS422 mode),Do I need any control lines like "RTS","CTS"?
any positive suggestion is welcome. best regards to you all
mike

That depends on how your driver and receiver are wired to your serial port.
