Hey all,

we are using an ADM2682 RS485 transceiver connected to a BeagleBone Black.

Data exchange is done via one of the uart interfaces. Data direction is

set by a GPIO

from kernel space.
Is there currently a driver available for EPICS for RS485?

Most settings could be done over the drvAsynSerialPort driver,
but for RS485 one also needs to set the struct serial_rs485 which is not
implemented in this driver.

Does it make sense to add an option to use RS485 support?
Or would it be better to create a clone of the serial port driver for RS485?

Best regards,
Florian
