Hi, My project deals with sending data bits to a port through the parallel port. I am making use of dlportio.dll. I am referring to an example provided in http://yueda.issp.u-tokyo.ac.jp/weda/ruby/prnprtLX.rb. Can anyone please explain me how the code words especially I have never come across Inpbyte.call(adrs)&0xff. Thanks!
