Subject: howto write to serial port
Date: Wed, 13 Nov 2013 10:09:07 +0800 [thread overview]
Message-ID: <20131113020907.GA18280@greatfirst.com> (raw)
I register a uart, But it does't appeared in /dev.
How can I open it and read/write it.
If I must use cdev->getc() and cdev->putc(). How to
get the cdev pointer which point to my registered uart.
