Assert RTS before polling out a character, |
|
and deassert RTS after the character is polled out. |
|
Please note that this is not suitable, when polling out several characters. |
|
Please use uart_drv_cmd with CMD_POLL_ASSERT_RTS before polling out. |
|
Then use CMD_POLL_DEASSERT_RTS to resume normal operation after polling. |
