These two talk over wire, using some protocol...some request-response bytes structure that we invent :)) Now the next thing is...what is busybox and can I use it in this case on the SBC? and where to find such SBCs.... Any pointers... ? the search continues :)) Recently I have realized that almost all problems in this world...are a form of search...No wonder the company that mastered search is a "G"iant now. 2) Going the ST way is not recommended (BTW its called Structured Text) ...because only a compiler will not be enough, we'll have to come up with some way of debugging... It would be like creating a whole new language. -- Thanks and best regards, Vishal Sapre --- "Life is 10% how you make it, and 90% how you take it" "बहुजन हिताय, बहुजन सुखाय (Benefit for most people, Happiness for most people.)" --- Please DONT print this email, unless you really need to.
