Hardware handshake on serial line

Hi.

I tried to use hardware handshake on the serial port of the iPAQ but
it seems not to work correctly. I tested the same code on my desktop
PC and it worked quite well. I use the original Compaq cradle.

Any ideas?

Here's the code:

  struct termios terminal;

  int handle = open( "/dev/ttySA0", O_RDWR | O_NOCTTY );
  tcgetattr( handle, &terminal );

  cfsetispeed(&terminal,B115200);
  cfsetospeed(&terminal,B115200);

  terminal.c_cflag |= CRTSCTS | CS8 | CLOCAL | CREAD;
  terminal.c_iflag &= ~IGNPAR;

  terminal.c_cc[VMIN] = 1;
  terminal.c_cc[VTIME] = 0;

  tcflush(handle, TCIFLUSH);
  tcsetattr(handle,TCSANOW,&terminal);
