	Note that the documentation of dial (3C) is wrong (at
least in my manual).  It says
	int dial(call)
	CALL *call;
when it should read
	int dial(call)
	CALL call;

	Here is a sample program that works.

#include <stdio.h>
#include <dial.h>

main()
	{
	CALL call;
	int error;
	unsigned sleep();

	call.attr = NULL;
	call.baud = NULL;
	call.speed = NULL;
	call.line = "/dev/ph0";
	call.telno = "9+4497455";
	call.modem = NULL;
	if((error = dial(call)) < 0)
		{
		printf("dial failed %d\n", error);
		return;
		}

	sleep(30);
	undial(error);
	}
