[ale] Socket Programming

[ChrisF at computone.com (Chris Fowler)]

Vernard,


You know much about Win32 programming?


I need to sucessfully run this piece of UNIX OK code in winbloze
/* terminal.c
??*
??*?? Small program to allow running of an excutable 
??*
??*?? Arguments:
??*?????????? ?????????????? argv[1]: PORT to be input and output
??*?????????? ?????????????? argv[2]: Console application to execute on the serial port defined
??*
??*/
???? 
#include <fcntl.h>
#include <stdio.h>


int
main(int argc, char *argv[])
{
?????????????? ?????????????? int fd;


?????????????? ?????????????? /* check arguments */
?????????????? ?????????????? if(argc != 3)
?????????????? ?????????????? {
?????????????? ?????????????? ?????????????? printf("terminal [serial port] [command shell to execute]\n");
?????????????? ?????????????? ?????????????? exit(1);
?????????????? ?????????????? }


?????????????? ?????????????? 
?????????????? ?????????????? /* Open Serial Port */
?????????????? ?????????????? if((fd = open(argv[1], O_RDWR)) == -1)
?????????????? ?????????????? {
?????????????? ?????????????? ?????????????? perror("terminal: OPEN COM");
?????????????? ?????????????? ?????????????? exit(1);
?????????????? ?????????????? }


?????????????? ?????????????? 
?????????????? ?????????????? /* Set STDIN, STDOUT, STDERR to the serial port */
?????????????? ?????????????? dup2(fd, 0);
?????????????? ?????????????? dup2(fd, 1);
?????????????? ?????????????? dup2(fd, 2);


?????????????? ?????????????? /* Execute the command specified */
?????????????? ?????????????? execl(argv[2],argv[2], 0);
?????????????? ?????????????? 
?????????????? ?????????????? /* If we are here, there is an issue! */
?????????????? ?????????????? perror("terminal");


?????????????? ?????????????? return 1;
}


What happens:


cmd.exe comes across COM1.?? But, on terminal, I can not type anything and it
appears that cmd.exe has terminated.?? Sorry for the windows post.


Any help would be appreciated.


Thanks,
Chris

By far the most in-depth book for doing any unix network programming is the
Stevens book. A must have book in my library.
