that connects to my serial port , I can speak to it with minicom. ( i am on centOS5.3 )
and it spits out a string.
Sensor 1 +72.38 DegF Hi +77.56 DegF Low +29.75 DegF
, it does this over & over.
What I would like to be able to do is.
Capture that string into a var $spitout.
parse $spitout for the num that is the temp ( ie: 72 )
and put that into a var $temp
and if temp is greater than ...80 then send an email.
content of the email would be $spitout.
so -- i can write send an email with perl , and I can evaluate 2 numbers with perl....into an if that will send the email...
But I am unable to snag this output into any form
I have read that my com port can be treated as a file
cat dev/tty0 > a file
but I cannot make that work
I wonder if what I am trying is impossible or if there is a way to ' read ' and evaluate the output of the dev/stty0
and if a inString num is greater that another num do something.
First I have to be able to ' get a hold ' of the info that i can see in the terminal win.
thanks
