main:
TX_BYTE theTemp
TX_BYTE setTemp
TX_BYTE tHold goto main


TX_BYTE:
  Flo = 1             'alert max 1483
   Pause 1
       Temp1 = __PARAM1
       SEROUT Sio,baud,temp1
  Flo = 0
RETURN

I can send 3 bytes one right after another from the SX to the stamp using Jon's example code above.  It works great!

The code below does not work for me.  Should I be able to ably the same idea as above and have it work?  

main
RX_TEMP setAcHi
RX_TEMP setAcLo
GOTO MAIN

RX_TEMP:
temp1 = __PARAM1
  SERIN sio, baud, temp1
RETURN

This format works ok but it seems like the one above should work too.

main:

RX_TEMP goto main

RX_TEMP:

Steve,
 In the example that doesn't work, it looks like you setting up to do a SEROUT but then you do a SERIN ?
 For instance why would you do "temp1 = __PARAM1" before a SERIN that is going to change the value of temp1 ?
 I think you want to do this:

 
RX_TEMP SUB 0 main:
 setAcHi = RX_TEMP
 setAcLo = RX_TEMP
 GOTO main
RX_TEMP:
 SERIN sio,baud,temp1
 RETURN temp1
Bean.

That makes a whole lot of since when you put it that way, I will give it a try.  Wow I would give anything to be half as sharp as you guys.  Believe it or not you guys have brought me along ways.

THANKS!
