Question, i.MX35 UART / watching DSR

Hi team,

 

I would like to ask about UART functionality of i.MX35.

My customer is developing their own i.MX35 board.

And they want to use UART as full RS232C communication.

They want to know how to watch DSR level.

The reference manual of i.MX35 says that the transition of DSR signal can be seen by interrupt in DTE mode.

But they want to know how one can watch the current Hi/Low level of DSR input signal.

Are there any ways to watch the current level of DSR, like reading some kind of register?

 

Thanks,

Miyamoto
