capture/repeat data ?

[Sam]

Please check out this thread: http://www.picbasic.co.uk/forum/show...=hyperterminal

This is where I found the code I'm trying and they say a MAX232 isn't needed and I can read the data from the 12F675 in hyperterminal with only a 1k resistor in line with pin 2 direct to the pc which is running hyperterminal.

However, I cannot get anything to show up in hyperterminal when I try typing on that pc. Nothing that I type shows in the hyperterminal window regardless if the DB9 is connected to the 12F675 or not. This is the same pc that I've used to communicate with the elm322 and when doing that,I'm able to enter characters in the h/t window.

I'm certainly not doubting your previous statement at all but the guys in the thread above seem to have it working without a MAX232 chip so I thought it would work with my pc (laptop).

The reason you see what you’re typing with the elm chip is because it is echoing the characters you’re typing.

In HyperTerm under Properties, there is a Settings tab. Under that there is ASCII Setup button and a check box that says Echo Typed Characters Locally. Check that box and try it again.

AND there's some chance it don't work as their internal OSC is sometime pretty poor. You may need to calibrate it AND/OR using the DEFINE OSCCAL_1K 1

DEBUG is recommended for those nifty PIC.

Hi,
I had tried the echo setting but nothing, I've tried every setting I can think of in H/T and still no characters show up in window.

mister-e,I'm fairly sure I have the define already in the code.I think it's something with the H/T because no matter what I do, nothing.

Does the tx line from the pc need to see a weak pull up or down or something before the typing will show up?

I'm going to go see if I can find a MAX232 chip and try that.

Thanks for your patience and help!

Tie CTS and RTS together.

[Sam]

I had to do 2 things, 1-tie cts and rts together,2-switched from my old HP laptop that I've been using for the comms and tried my newer Compaq laptop that I've been using to program PICS and for internet.

So now it's working,finally, cts and rts tied together and communicating with a newer pc. THANK YOU!

I do have another question, in the code where achar="A",how can I get more than one letter to work in place of "A" ? Such as something like 8A 45 A0.

Thank you all very much,
Sam

Nevermind, I remembered to re read the manual.

I did away with "Achar var byte" and achar="A"

And added this:

SerIn rx_pin,N9600,["8A 45 A0"]

I think this is right,seems to work???
