HSEROUT No Output Problem

[CocaColaKid]

I have a problem that I can not seem to figure out. If I use the line of code:

hserout [sign,dec3 temp/10,".",dec1 temp//10,10]

I get nothing display in my serial window however it says that it is receiving bytes. If I remove the "sign" from the line it works fine. Can someone shed some light on this one for me because it is driving me nuts.

Have you tried using the DEC modifier before sign?

I load the variable with:

    if temp.8 = 1 then                          ' If bit8 of temperature is set then its negative		
     sign = 45                                  ' Indicate temperature is NEGATIVE
     temp.lowbyte = temp.lowbyte ^ 255	        ' Reverse the bits of the lowbyte of TEMP
     sign = 160                                 ' Indicate temperature is POSITIVE
	endif

If I use DEC then my output is messed up. I did try it though and it does output.

Try this;

if temp.8 = 1 then                          ' If bit8 of temperature is set then its negative		
     sign = "-"                                  ' Indicate temperature is NEGATIVE
     temp.lowbyte = temp.lowbyte ^ 255	        ' Reverse the bits of the lowbyte of TEMP
     sign = "+"                                 ' Indicate temperature is POSITIVE
	endif

Same thing, I tried this approach as well.

I don't understand what it actually is that I'm sending since there is nothing displayed in the serial window. It just keeps increasing by 6 bytes at a time.

[Bruce]

How do you know it's increasing if there's nothing showing in the serial window?

[CocaColaKid]

I'm using the Serial Communicator in MCSP which display TX and RX in the bottom status bar.

If you haven't already,double check each variable by re-sending each one individually,with and without LF,in combinations,to see if the answer falls out.The other possibility is the receiving program may have limits that are removing characters,like buffer size.
I use a program call Simple Terminal from BB Electronics.It runs in dos window,but displays everything.

I feel pretty dumb right now. If you look at the code there is no else if the if statement.

[Acetronics2]

if temp.8 = 1 then ' If bit8 of temperature is set then its negative
sign = "-" ' Indicate temperature is NEGATIVE
temp.lowbyte = temp.lowbyte ^ 255 ' Reverse the bits of the lowbyte of TEMP
sign = "+" ' Indicate temperature is POSITIVE
endif

> So, no sign if positive , or + sign if negative ??? ... doesn't really mean the same.

> And I'm wondering if "sign" value is defined somewhere else ...if positive !
