Question How to poll() for CTS-signal?

Hy friends,

to use poll() for reading and writing serial devices, pipes etc. is easy and works excelently.

Could I use poll() or an equivalent POSIX-method also to test the CTS-signal?

How could I get an asynchronous notification by Linux that the CTS-line was set?

Thanks!
Regards
Egon
