Tool/software:
Hi Experts:
Our HW design (based on the AM62P) provides several RS485 ports w/ the RE* (Receive Enable) pin of the RS485 transceiver tied to GND, i.e. the receive portion of the RS485 transceiver always enabled. As such, we are always receiving what we're sending.
How can I tell the corresponding Linux driver (drivers/tty/serial/8250/8250_omap.c) to turn off the UART receiver (presumably through bit UART_ECR[3] RX_EN) while sending?
Thx,
Chris.
