I think you you will read raw from the device, please set 

	t.c_iflag		= 0;
	t.c_oflag		= 0;
	t.c_cflag 		= B4800 | CS7 | CLOCAL | CREAD | PARENB;
	t.c_cc[VMIN]		= count;
	t.c_cc[VTIME]		= time; 	
	t.c_cc[VSTOP]		= 0;
	t.c_cc[VSTART]		= 0;
	t.c_lflag		= 0;
	t.c_oflag		= 0;

VMIN and VTIM are most probably described in a serial HOWTO

Particulary, I think ICANON is wrong in this context.
Use select(2)  ;-)
