Re: ioctl(TIOCMGET) on Lite5200

I'm having a problem with a specific argument of the
ioctl function, which is ioctl(TIOCMGET).
I wrote a simple routine which just reads or writes the
RTS pin.
It worked OK on my Red Hat 9, under x86, but when I try
to run it on a Lite5200 using denx kernel 2.4-25, it
keeps saying "TIOCMGET failed: Invalid argument" and

Well, that says it all: the TIOCMGET ioctl() is not

available for the

5200's PSC uart driver.

Best regards,

So, if the 5200 series don't support TIOCMGET and
TIOCMSET ioctl() (nor TIOCMBIS and TIOCMBIC, I've just
tried them), what could I possibly use to get/set the
control pin RTS in my Lite5200?...
Is there any other system call or function that
accomplishes that?

Thank you very much.
