  Jay, when you say decimal, do mean something like 123.45? If so, the decimal is 6 bytes long. How many bytes are you expecting before a timeout? What is the min and max value of the decimal?

  I think he means "denary"!

  Thanks for your replies, well for DecIn I am assuming "long" --> 4 bytes

  DecIn is string command that waits for a <cr>. Then it handles the string.
  
  If you need a 4 byte LONG value then create a loop that reads, validates, and stores the 4 bytes in memory. Use the rxbyte method of the Full-Duplex Serial object to read the bytes without blocking.

  You've started another identical thread in the General Discussion forum. This is against forum rules. Do not do it again!
  
  Since ParallaxSerialTerminal has an rxcheck routine, you can just add the same rxtime routine routine to it that you showed. DecIn uses the routine StrInMax which uses CharIn which uses rxcheck. You could substitute a call to rxtime for the call to CharIn to come up with a StrInMaxTime routine, then you'd have DecInTime call StrInMaxTime.

  PUB StrInMaxTime(stringptr, maxcount, mstime) | temp
  {{Receive a string of characters (either carriage return terminated or maxcount in length) and stores it (zero terminated)
  starting at stringptr.  Waits until either full string received or maxcount characters received.  Times out in mstime milliseconds.
  Returns true if a timeout occurred, false otherwise.
    Parameters:
      stringptr - pointer to memory in which to store received string characters.
                  Memory reserved must be large enough for all string characters plus a zero terminator (maxcount + 1).
      maxcount  - maximum length of string to receive, or -1 for unlimited.
      mstime - timeout in milliseconds (for each received character)}}
      
    repeat while (maxcount--)                                                     'While maxcount not reached
      if (temp := rxtime(mstime)) < 0                                           ' Stop on a timeout
        byte[stringptr]~                                                                ' Zero terminate string
        return true
      if (byte[stringptr++] := temp) == NL                                      'Get chars until NL
        quit
    byte[stringptr+(byte[stringptr-1] == NL)]~                                    'Zero terminate string; overwrite NL or append 0 char

  Sorry for that, actually its my first time and I posted my question in General discussion forum... then realize that I should need to put in Propeller forum as my question is specific to spin.
  meanwhile thanks for the support, will take care in future.
  
  Thanks
  Jay
