Following is a small program that gives an example of placing outgoing
data calls using ioctl calls and the UNIXpc onboard modem.
Most of the changes I made to C-Kermit did exactly what this program does.
Basically, I created a new modem type in ckudia.c, and had the new type make
calls to ttdial in ckutio.c. Could somebody post an example of using the
dial(3c) routine for the OBM? Anyway, ttdial did the following:
--------------------------- Cut Here ---------------------------------
/* See phone(7) for more details */
#include <sys/types.h>
#include <signal.h>
#include <sys/phone.h>
#include <fcntl.h>
#include <stdio.h>
static int fd;
static struct updata phc;
static char digit;
void tthangup()
{
ioctl(fd, PIOCDISC, &phc);
close(fd);
exit(1);
}
main(argc, argv)
int argc;
char **argv;
{
int i;
char *s;
if(argc != 3)
{
fprintf(stderr, "usage: dial device tele#\n");
exit(1);
}
if((fd = open(argv[1], O_RDWR | O_NDELAY)) < 0)
{
fprintf(stderr, "error opening device\n");
exit(1);
}
/* ttdial stuff */
signal(SIGQUIT, hangup);
signal(SIGINT, hangup);
signal(SIGHUP, hangup);
ioctl(fd, PIOCGETP, &phc);
phc.c_lineparam |= DTMF;
phc.c_lineparam &= ~INCMNG;
phc.c_waitdailtone = 5;
phc.c_waitflash = 500;
phc.c_feedback = SPEAKERON | NORMSPK;
ioctl(fd, PIOCSETP, &phc);
ioctl(fd, PIOCOFFHOOK, &phc);
while(1)
{
ioctl(fd, PIOCGETP, &phc);
if(phc.c_linestatus & DIALTONE)
break;
}
printf("Dialing %s...\n", argv[2]);
s = argv[2];
while(*s)
{
digit = *s++;
ioctl(fd, PIOCDIAL, &digit);
}
digit = '$';
if(ioctl(fd, PIOCDIAL, &digit) < 0)
hangup();
printf("connected\n");
/* then ttdial would return, but this is an example */
pause();
hangup();
}
------------------------- End Example -------------------------
