vxworks serial operation

zijing86

I am a novice, just contacted vxworks, and perform 2 serial communication under vxworks
Open using tty0, tty1, etc.
And call the read function to read the serial data
Now I do n’t know when the serial port receives the data, so the read function is always stopped there. How can I read the serial port data to avoid an endless loop? (Due to limitations, it is not considered to read the data separately.)

Can you be more specific?

select

Because the status of the serial port is wrong, you can see if the status is wrong, otherwise you have to wait there!

It is best to attach the original code

Wait for I/O device with select
