How To Find If Modem Is Still Connected

[Rohit Mehrotra]

How do I find out inside a C program (which dials out on a serial
port) as to whether the modem is still connected to the remote 
machine, or for some reason it has lost connection.

i.e if the carrier detect signal is still on or not. I think that
some ioctl calls would have to be used, but I am not sure which
and how ?

Please EMAIL any helpful responses.

Thanks in advance.
