Understanding serial terminals

English Programming/Scripting
1

Hi all,
I am using a special printf statement that prints the following to the serial port (for advanced users, there is a printf library for telosb programming that writes to the serial port).

What I am printing is
printf("Hi I am writing to you from my TinyOS application!!
");
printf("Here is a uint8: %u
", dummyVar1);
printf("Here is a uint16: %u
", dummyVar2);
printf("Here is a uint32: %ld
", dummyVar3);
printfflush();

but what I am receiving has some characters that I do not understand…

perhaps it might be something funny with my configuration that is

Can someone please help me understand what these characters are and how I can see the string the way I am sending it?

I would like to thank you in advance for your reply

Regards
Alex

When I look at this link, I don’t see the image. I expect it wants me to
enable Javascript, which I’m not about to do. Please post it to a
website that displays images using HTML.

Hi, just a quick question : are you sure you set the same xfer parameters (parity etc) on both terminals (sending and receiving) ? HTH Lenwolf
