Matlab programmers for reading data from parallel port:

General Format :

Parport =digitalio(„parallel‟,‟LPT1‟); For enabling parallel port .
Hwlines =addline(parport,0:3,x,‟in‟); x denote data,control or status port value assigned zero ,
oneor two. In denotes the direction of port.
parport=digitalio('parallel','LPT1');
hwlines=addline(parport,0:4,1,'in');
k=getvalue(hwlines)

Matlab programme for write data:

dio = digitalio('parallel','LPT1');
addline(dio,4:7,'out');
val1 = getvalue(dio.Line(1:4))
val3=binvec2dec(val1)
