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.
