我的发展目标是,有两家物理序列港口,位于/dev/ttyS0和/dev/ttyS1。 我也期望界定/dev/ttyS2和/dev/ttyS3。
Using stty -f /dev/ttyS0 and S1 reports the configuration of the two serial ports and reports something menaing "doesn t exist" for S2 and S3.
硬件设计师谈论的是向主机上建的航天港口提供U。 他们是外线和路边的亚银9号连接器,内部没有UV。 US-对空中连接的数量没有保障,我知道设计“many”而不是“many”的足够。
因此,在建立我的港口服务器“ da”时,我需要能够确定哪一种脂肪,哪一种脂肪是“real”,哪些是n t。 是否有任何地方存在。 如果是“无标记”的话(实际上,是常设法院内部真正的U对手)?
是否有比开放()更好的办法,并审查其产出,以确定序列港口的地位? 是否有一份CAP供作准?
感谢!
相对使用的“C-API”是tcsetattr(3)和tcgetattr(3)。
