[go-nuts] timeout with bufio.Scanner & Scanner.Scan()

[Trig]

I'm currently reading ASCII data from a serial port using the bufio.Scanner 
(since what's coming back is a line at a time, it's convenient w/ reading 
using the Scanner.Text()).  Problem is, the for loop I use to process the 
reads lock at the Scanner.Scan() call.  Is there a to implement some for 
loop that utilized the scanner while utilizing a timeout?

I've tried:

for {
   select {
      case <- time.After(time.Second * 3):
         response <- &Response{
            Error: fmt.Errorf("command call took to long for a response"),
         }

         break
      default:
         myScanner.Scan()

         if myScanner.Text() == "OK" {
            response <- &Response{
               Content: []responseLines,
            }

            break
         }
      
         responseLines = append(responseLines, myScanner.Text())
   }
}

Of course, after looking at it... it makes sense why it's not working as 
the loop locks at myScanner.Scan() if there is nothing further to Scan.  
Any help or examples would be appreciated.
