Subject: Enabling auto RS485 half-duplex control
Date: Wed, 17 Dec 2008 22:24:13 +0100 [thread overview]
Message-ID: <200812172224.13608.mfuchs@ma-fu.de> (raw)
Hi,
some Exar UARTs like the XR16C2850 support a feature
called auto RS485 half-duplex control. In this mode the
RTS line has a special role when using the UART for
RS485 communication.
I did not find a way to enable this mode through the
standard serial driver. The UART is is detected correctly
but there seems to be no way to enable this mode
out of the box.
So what's the best way to implement this?
A new ioctl? Any idea?
Matthias
