I'm just curious and assuming it not a trade secret, how many servers does it take to run CP, aprroximately?

in my C# program(I mainliy use SerialPort class),I input "at" in a textBox,then the program send "at" to serial port(the other end of serial port is a modem which is connected to my computer by a data line),but when i click receive button,the message I receive from serial port is the same as what I input,namely "at",not "ok",why?who can answer my question?How I solve this problem and get the right response "ok" from serial port?
next is my code:
public partial class Form1 : Form
{
private SerialPort sp = null;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
sp = new SerialPort("COM1");
sp.ReadTimeout = 5000;
sp.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
sp.Write(textBox1.Text);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void button3_Click(object sender, EventArgs e)
{
try
{
/*string text=null;
char[] buffer = new char[10];
sp.Read(buffer,0,6);
for (int i = 0; i < buffer.Length; i++)
{
text += buffer[i];
}
textBox2.Text = text;*/
/*string text = null;
char t = (char)sp.ReadChar();
text+=t.ToString();
while (true)
{
t = (char)sp.ReadChar();
if (t == '\0') break;
else text += t.ToString();
}
textBox2.Text = text;*/
string text = null;
byte[] t = new byte[20];
char[] c = new char[20];
sp.Read(t, 0, t.Length);
sp.Read(t, 0, t.Length);
c = Encoding.ASCII.GetChars(t);
int i;
for (i = 0; i < c.Length; i++)
{
if (c[i] == 'O' || c[i] == 'K')
text += c[i].ToString();
}
textBox2.Text = text;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}

Your modem probably has 'echo' switched on. Hence you send
"AT\r" and get back "AT\r\nOK\r\n"
To forestall your next question, if your modem uses the standard AT command set, you can probably send
"ATE0\r" instead of a plain "AT". That will turn echo off, although of course, your initial command will be echoed back to you, while subsequent ones won't.

Thanks for answer my question!But the problem is not what you said,I send "at e0\r",and then I send "at\r",but the message I receive from the SerialPort is "at e0\rat\r",that's very curious!Waiting for you reply!Thanks you very much!

Hmm. My modem programming is rusty. I think it may be AT&E0 that you need to turn off echo.
Have you got a reference manual for the modem? Failing that, you could try google...

Hi,
If you have trouble with serial port software in connection with modem,
then I strongly suggest you split the problem in two parts:
- test you cable and modem using an existing app, such as HyperTerminal;
this will also help you in learning modem commands (use on info from Google)
- develop your serial port code without a modem, use a second PC (maybe again
with HyperTerminal; and with a null modem, or null modem cable) or something
else
Only once you got both parts sufficiently solved, try to combine your app
with the modem.
BTW: I advise you to log all serial data (both in and out) in a file using
both hex and ASCII while debugging (and to leave the code in, but switch it off,
once you think it works adequately).

Hi,
I have to build an application that will run as a windows service. It will recognise when a USB mass storage device has been connected to the windows machine, and instead of the standard windows processing that creates a removable drive, a simple custom windows explorer interface will be displayed. The net effect is the ability to be able to plug in a USB mass storage device and give the user the option to look at the files on the device before windows explorer and the windows o/s creates a removable drive. I have to built a custom file manager that can do cut, copy and paste operation. I have SDK for this. Does anybody have any idea regarding this?

My idea is that you ask in the appropriate programming forum.

Strip the machine down to nothing but a poser supply, motherboard, CPU, RAM and video card. Try to power it up. If you still get nothing, you've got major problems. You'll be swapping these parts out one-by-one, starting with the power supply, until you find the part(s) that is(are) failing.

Just buy a new system. The way you're asking the question implies you don't have the knowledge to fix it.

Try to type parallel port inside the CP article search box, maybe any magical will happen!

Could Any body tell me about Pentium 5. Is it launched in the market. Is it available to purchase
Nitin Jenwal

There is no Pentium 5. After the Pentium 4, Intel did a complete redesign of their microarchitecture and developed the "Core" series which is what the Core Duo and Core 2 Duo processors are based on. The Pentium line is dead.

It's not a complete redesign. The Core series is derived from the Pentium-M which is an enhanced P3 design.

Hey all,
I have several projects that I want to complete that involve USB devices. I was wondering if there is any generic way to grab the output and input to any USB device.
I'm not looking for anything too clean, just something that works for the moment, as I will spend time adjusting the method to my various projects.
At any rate, is there a generic way to access the output and input of any USB device in windows? (or even just grab the output?)
thanks,

No, there isn't. USB is not a port, like serial or parallel. It's a BUS, just like the PCI bus you stuff cards into inside the machine. Communicating with any device on the bus requires you to go through the interface supplied by the drivers for that device.
|
|
|
|

Oh, Ok, thanks for explaining that, makes since now. Always wondered why USB was so different.
- thanks

I have a couple of USB boxes which support performing digital and analogue I/O.
They didn't come with drivers (and as I run FILEMON when I install stuff, I can be reasonably sure of that!). However, there is an API library supplied to communicate with the hardware.
Presumably this uses a standard MS-supplied driver to provide user-mode access to allow tx/rx of requests/replies sent to the devices?

You need the documentation on that SDK, otherwise, it's useless. That SDK is your only method of communication with the devices.
