You think everything is a bad idea. And don't often back up your arguments. You were spitting feathers about minicom the last time our paths crossed.
First off, yes, "minicom" is a POS, and I cry every time I hear it recommended to a newbie.
Or see a newbie using it (because he read somewhere that it was a good choice for a serial comm program in Linux). I feel it is my duty to point out that a) minicom is a POS and b) an easy, cheap alternative exists (screen).
Second, I don't "back up my arguments" because I am not here to argue with you. You obviously believe what you believe and I doubt I can change that, nor do I have any desire to do so. I am here for the newbies.
Finally, I can think of 3 obvious reasons why using cron as you describe is a bad idea. They are so obvious that I won't bother writing them out now. Maybe at some point, when I'm really bored, I may type them out (and paste them in here).
And that's that...
And some folks need to stop being fanboys and see the forest behind the trees.
(One of the best lines I've seen on this board lately)
