Serial comunication problem

[Charles Linquis]

Also, make certain that Hyperterm is set for Flow Control = None

Are you adding the '#' before the variable?

And if you are using the built-in oscillator on the 16F676, are you sure your OSCCAL value is correct?

Firs one thanks to all for fast answer.
Yes I have checked all things posted and a lot of times.
But nothing work.

Maybe is a problem with a Breadboard thet collect noise ?

I know it hard to say what check, but all seem fine and at
same time nothing work!

I am very confused because I have made a lot o circuit
with PIC in assembler and basic, with motor, with display,
with PWN dimmed ligght, and ever have worked fine,
but now with a silly serial debugging purpose nothing
work.
I am very frustated!

Post you code and configs along with a schematic.
Everyone is guessing as is.

Hello,
Thank for reply and sorry for the late to answer but I was away for job.

I don't have much to to make experiment but I have try to change the
cable and the main circuit.
All is same I will get back the same garbage but...

Now i try to send the word "Hello" and now I get back on screen PC the
exact number of chars but with non ascii format like '¨µ¼´¿".

Yesterday I don't know how, maybe some change to prog or same hack
on circuit, for a short time I have get back the correct string on screen!
"hello"hello"hello"...

After that I have made some change and now all is come back in the
same garbage!

In anyway this is the source:
------------------------------------------------------------------------------
ANSEL=0
CMCON=7



TRISA = %11110000 ' Set PORTA to all input
TRISC = %00000000 ' Set PORTA to all input


Include "modedefs.bas"

DEFINE OSC 4

DEFINE DEBUG_REG PORTC
DEFINE DEBUG_BIT 1
DEFINE DEBUG_BAUD 2400
DEFINE DEBUG_MODE 0

DEFINE DEBUG_PACING 1000

Clear
Pause 1000

Cont var Byte

Cont = 0
Mainloop
PAUSE 1000
Cont = Cont + 1
Debug "Hello"
PORTC.2 = 1
PAUSE 1000
PORTC.2 = 0
goto Mainloop
------------------------------------------------------------------------------
And this the circuit:

I see you have a LED set to blink on for 1 sec, then off for 1 sec. Is the LED blinking and at the correct speed?

Hi Bert,

I have fogot to say, it is only a luminose control to see if all work well(I don't have put it on the scheme).
And yes it seem blink 1 sec and 1 sec no. It's hard to say just lookin at it
but the time seem correct yes.
