Serial Comms Buffer?

[koossa]

Good day

I'm using PIC16F877 @ 4MHz with a MAX232 for serial comms.
If I send the following data from my pic to PC every character with a CR + LF, I receive it at the PC side:
"*=123:010173D83398;
:|,E"

But if I do it again it looks like the existing data in the buffer does not clear and I receive the following:
"*=123:010173D83398;
:|,E*=123:010173D83398;
:|,E"

Is there a way that I can clear the buffer everytime after receiving the data?

koosa,

* what does your PIC code look like?
* what application are you using to capture the data on the PC?

Hi Ralph

Thank you for your reply.
I think the problem is at my PC Side.
When I use microcode studio's Serial Communicator it is working

Thx!

I guess you also use the BOOTLOADER ? In this case, be sure that the DTR line is disable.

well i guess you already know that anyway ;)http://www.picbasic.co.uk/forum/showthread.php?t=2669&highlight=vb

EDIT: DOH! sorry... should read your post better... consider the Ralph's question

Hi Koosa,
Check the settings for something regarding an echo.
