I have a project I'm going to be doing on a microcontroller. I plan on having it interface with my computer over a USB serial connection. I tried doing the basic tests like putc(getc()), but I'm having trouble getting it to behave as I expect.
With that simple hardware-echo thing, many things just don't work. When I push enter, I just get a carriage return. Backspace does nothing. CTRL-C for breaking doesn't work either.
I'm using GNU Screen as my terminal emulator. How do I learn how to handle all of this(along with stty settings) so I can make a useful command interface on my microcontroller?
You will need to know what terminal type your Screen terminal is emulating so that you know what codes to send out the serial port. For example, if you set your terminal to VT100, you can check out this link which provides some VT100 codes
And for gnu-screen you might want to check this out as it contains an exhaustive list of ESC and control strings/commands that you can use.

I'm having a problem with getting this code to print out to file due to some undefined behavior. It seems that when I test it the output file opened but was empty. can anyone run it on their system and tell me if it work on your system or is it not working at all. Also can you provide me with the output file if you run it.
here is the code

and the data for the file

thanks
Per the code comments:
The compiler is supposed to be gcc, the system("PAUSE") won't "work" in most UNIXes. It looks like it is meant to be compiled under cygwin running on a Windows PC, or under Linux. Not Windows. The PAUSE part makes very little sense, since that is largely a DOS command. You had to have copied the code from someone, it looks like the code scores competing ice skaters. The probability that it is production code is low.
Where did you get the code, and what assignment is this supposed to be for?
Suggestion:
See www.cygwin.com to install cygwin on your PC.

I have practically no experience with programming outside of ide's (Microsoft Visual Studio, netbeans and eclipse) and I am beginning to learn C programming. I have adequate experience with C++ and Java. I have downloaded gVim 7.3 and am looking for some guidance on how to program in C with vim. I do not even know where to type code with vim! I am completely lost and am looking for instructions to run simple command-line programs such as hello-world (to start). Also, would notepad++ be of any use?
Somebody please show me the world of C programming and Vim
Usually its done like this - you open up a shell window, set your compile enviroment configuration. Then open any files you are working on with gvim to have a C syntax highlighting available, modify them and save. Get back to shell window repeat make command or whatever you need to compile and link application.
The usefull extension for me was ctags, which allows to browse declarations. You dont get the comfort of code completions, intelissence, on-the-fly error messages or list of function parameters, but I didnt miss that much eitherway.

These days I'm aware of the powerful web browser. In order to know what happend behind the screen. I want to write a simple web browser. But When I try to find document about that. Nothing find! Any one konw how to write a simple web browser or know where is the book will be useful. Please tell me !
Thank you very much!
Start off with a simple browser -- e.g., look at existing text only ones like lynx or w3m. Once you've got them cracked, then you can work up to adding graphical elements. It can get complicated fairly quickly, so make sure you've read the appropriate RFCs for HTTP and the W3C standards as well. These aren't light reading material though :-)
Here's something to get you started:

C might not be the best language for this job.

I read a lot of books about C/C++ in Linux and write simple programs. Now I want to try myself with some project. What you can recommend to? (Sorry for my bad English)
If you don't know what to do and just want to get a little experience, try implementing the towers of Hanoi, it's a classical programming exercise (the Wikipedia article might seem frightening at first sight, but the actual algorithm is dead-simple and you'll find lots of material about it online, even a lot of sample implementations). First, start with a text-only solution that just prints numbers. Then, try to "draw" the towers using ASCII art. You can also do this with a GUI, but as a novice it's easiest to start with text-based version.

I would consider myself a fairly competent programmer with experience in Java and VB.net. My latest swim around the programming lake is having me modify a program written in C. (The program is Wireshark, an open source network analyzing tool.) I followed the instructions here http://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin32.html and simply don't know where to go from there. I'd like to use Visual Studio 2008 to work with the code if possible, but will do whatever is necessary. (I'm a total noob at using command prompt to do anything though.)
If you followed those steps, then you've built it. I'll copy Section 2.2.10 here.
2.2.10. Build Wireshark
Now it's time to build Wireshark ...
If you've closed cmd.exe in the meantime, prepare cmd.exe again
nmake -f Makefile.nmake all to build Wireshark
wait for Wireshark to compile - this may take a while!
run C:\wireshark\wireshark-gtk2\wireshark.exe and check if it starts
Just make changes in the code, do these steps over again, and presto! you've modified the program. You may want to bone up on C debuggers if you're doing anything very complicated.
