hello

i need a c or c++ program to read data from serial port connected to sick pls laser scanner.model is 200-113.

I have tried several programs in vc++,c,c++ but no one is able to read data serial port.

In one program i am getting msg

xxx.exe:MFC42D.dll:0xc000000: Access violation

When debugged i get

No matching symbol found :kernel32.dll

user32.dll

msvcrt60.dll

and so on.

And finally i get the program ends witih 0x0 code.

in another program it is saying bios.h not found

Whiel in anotehr it says could not able to find outportb()

I dont know the problem is.

But i need one program for this special case ie reading data from serial port connected to sick pls 200-114 laser scanner.

Eagerly waiting for answer

I have some c++ serial port code that does what you want. Email me and I will send it to you. I have used it for a few apps. and it seems to work just fine.

C or C++ program to read data from serial port?ie internet explorer

i guess both can be used.. there is some library which provides some methode to read data from serial port
will have 2 machines hooked up via the COM1 ports.

1 machine running windows having a hyperterminal session opened and the other machine running Linux having my program running.

I want to able to type a character into the hyperterminal window and have the character displayed on the Linux machine.

Im very new to C programming but heres what i have for my program so far, just not sure how to read the input and display it:

#include %26lt;stdio.h%26gt; /*Standard input/output definitions*/

#include %26lt;string.h%26gt; /*String function definitions*/

#include %26lt;unistd.h%26gt; /*Unix standard function definitions*/

#include %26lt;fcntl.h%26gt; /*File control definitions*/

#include %26lt;errno.h%26gt; /*Error number definitions*/

#include %26lt;termios.h%26gt; /*POSIX terminal control definitions*/

int open_port(void)

{

int fd; /* File descriptor for the port */

fd = open("/dev/ttyS0", O_RDWR | O_NOCTTY | O_NDELAY);

if(fd == 0)

{

perror("open_port: Unable to open /dev/ttyS0 - ");

}

else

fcntl(fd, F_SETFL, 0);

return (fd);

}

/*Configire port*/

struct termios options;

/*Get the current options for the port*/

tcgetattr(fd, %26amp;options);

/*Set the Baud rates to 19200*/

cfsetispeed(%26amp;options, B19200);

cfsetospeed(%26amp;options, B19200);

/*Enable received and set local mode*/

options.c_cflag |= (CLOCAL | CREAD);

/*Set new options for port*/

tcsetattr(fd, TCSANOW, %26amp;options);

/*Set data bits*/

options.c_cflag %26amp;= ~CSIZE; /*Mask the character size bits*/

options.c_cflag |= CS8; /*Select 8 data bits*/

/*Set RAW input*/

options.c_lflag %26amp;= ~(ICANON | ECHO | ECHOE | ISIG);

/*Set Raw output*/

options.c_oflag %26amp;= ~OPOST;

/*Set timeout to 1 sec*/

options.c_cc[VMIN] = 0;

options.c_cc{VTIME] = 10;

/*Code to read input goes here*/

close(fd);

Can anyone advise on this?

Thanks
Here is one program:

You should know what is expected from your input device, though.
